Mont Blanc

 

Location: border of Italy and France Map

Elevation: 15,770 ft (4,808 m)

 

Mont Blanc (Mont Blanc in French and in Arpitano), with an altitude of 4807 m above sea level (according to the last official measurement carried out on 3 December 2017), it is the highest mountain in the Alps, Italy, France and even in Europe, according to some geographical conventions, hence the nicknames of roof of Europe and of King of the Alps, sharing a place among the so-called Seven Peaks of the Planet together with Mount Elbrus in the Caucasus.

Located in the sector of the North-Western Alps, along the alpine section of the Graian Alps, on the watershed between Valle d'Aosta (Val Veny and Val Ferret in Italy) and Upper Savoy (Valle dell'Arve in France), in the municipal territories of Courmayeur and Chamonix-Mont-Blanc, gives its name to the massif of the same name, belonging to the subsection of the Mont Blanc Alps. Predominantly of a granite nature, bristling with pinnacles and ridges, carved by deep valleys through which numerous glaciers flow, it is considered a mountain of great attraction for international mountaineering and, from the point of view of mountaineering historiography, the birth of the alpinism itself coincides with the date of his first ascent: 8 August 1786.

 

Geography

From the Italian view, the Roof of the Alps is not all that flashy compared to the other peaks that surround it. Unlike the other great giant of the Alps, Monte Rosa, visible throughout the north-western Po Valley up to the first Apennine hills, Mont Blanc appears only at the last moment along the road to Courmayeur, hidden by a myriad of satellites minors. Looking at it from the west, however, it is clearly visible from far away, from the heights of the French Massif Central, from those of the Vosges, from the heights of the Jura, from Switzerland, from the Black Forest.

It is perennially covered in snow and is located in the central part of a chain of mountains which extends 40 km in length and 8 to 15 km in width, over the territories of three different states, occupying an area of about 645 km²: the massif of Monte White. If we exclude the east wall of Monte Rosa di Macugnaga, the highest in the Alps, this massif contains some of the highest walls of the alpine system such as the Brenva and the north face of the Grandes Jorasses and forty peaks are grouped above the 4,000 m, with a third of the surface at an altitude of no less than 3,000 m. Over time, the action of erosive agents on the granite rocks has formed sharp ridges and pinnacle peaks of particular beauty which attract climbers from all over the world to the region.

While the French side descends slowly on a slope, the Italian side is formed by a steep and majestic granite wall which from the highest peaks falls to the bottom of the Ferret and Veny valleys. On this side there are the most difficult and demanding walls to climb. The inhabited places are located below 2,800 m, while the passes are rare and difficult, the lowest of which is that of the Giant at 3,359 m. Here are some emblematic peaks:

The Dente del Gigante (4,014 m) is one of the most famous peaks. It rises about 160 m above the characteristic snow gum.
The Grandes Jorasses: on its summit, about 1 km long, it groups together a sequence of six peaks, five of which exceed 4,000 m.
The Aiguille Noire de Peuterey (3,773 m) is one of the symbols of Mont Blanc on the Italian side: it rises directly from the meadows of Val Veny for a difference in altitude of 2,200 m; it is the most important peak of the Peuterey crest.
The Dôme du Goûter (4,306m). If the summit of the Grandes Jorasses is bristling with peaks, that of the Dôme du Goûter is completely flat and is the largest of all the Alps.
Mont Dolent (3,820m) is a pyramidal peak; curiously its summit is the meeting point of the borders of Italy, Switzerland and France.
the Spires of Chamonix, between 3,000 and 3,842 m, dominate the Chamonix valley and represent one of the most famous landscapes in the French Alps.

 

Height

Below the summit cap, under a blanket of ice and snow 16 to 23 m thick, at an altitude of 4,792 m is the rocky peak, located about 40 m further west than the summit itself. In 1740 the Swiss mathematician Nicolas Fatio de Duillier was the first to determine its height using the trigonometric system: according to his calculations, the White measured 4,000 m. Thirty-five years later, in 1775, using the same method as de Duillier, the English mathematician George Schuckburgh-Evelyn indicated the altitude at 4,804m. Through the barometer in 1787 Horace-Bénédict de Saussure measured 4,809.07 m while in 1844 the French physicist Auguste Bravais measured 4,810 m and in 1892 Joseph and Henry Vallot 4,807 m.

In August 1986 the orthometric measurement taken by satellite was 4,804 m. Subsequently, the official height was 4,807 m for a long time, to then pass in 2001 to 4,810 m; in 2003 at 4,808 m; in 2005 it was 4,808 m; in 2007 at 4,810 m; in 2009 4,810 m and in the last measurement in September 2015 at 4,808 m, lower than the previous measurement of 1.29 m. These variations are due to the winds which accumulate the snow on the top, consequently determining its height. If during the year there are fewer windy days than in the previous year, as a result less snow will accumulate, affecting its height. Due to the continuous variations of the ice cap, an official survey has been made every two years since 2001. The measurements are carried out by the provincial chamber of surveyors of the Haute Savoie in collaboration with a company specialized in GPS surveys. After the drought of 2003, the measurement carried out in the month of September of that year certified the height at 4,808.45 m and on that occasion it was ascertained that the summit had moved 0.75 cm to the north-west with respect to the position of the 2001.

During that measurement campaign, more than 500 fixed reference points were placed on the summit cap in order to precisely study the variation of the ice volume above 4,800 m which in 2003 was 14,600 m³, 14,300 m³ in 2005 to arrive to the current 24,100 m³. Mont Blanc is the highest mountain in the entire Alpine chain and also considered the highest in Europe. However, if the Caucasus is considered as the south-eastern geographical limit of the continent, those located in Russian and Georgian territory are cited as the highest peaks in Europe, such as Elbrus which culminates at 5,642m, Dykh Tau with 5,203m, the Shkhara at 5,200m and Kazbek at 5,047m.

 

Geology

The mountain complex of the Alps was generated during the Tertiary Era thanks to the thrust of the African and Asian tectonic plates, through a process of vertical elevation. About 300 million years ago, during the Hercynian orogeny, a large granite intrusion formed the basic structure of the current Mont Blanc massif. Modern surveying methods highlight today how the elevation of the Alps continues incessantly and still overcomes the effects of erosion. Metamorphic rocks (gneisses, mica schists and calc schists) emerged around the granite (protogynous) nucleus. The most frequent rocks are:

the granites, which are distinguished in the central part of the Massif by the spire-shaped crests and the acute shapes of the reliefs. Although very hard, this rock does not resist the effects of erosion caused by ice.
Metamorphic rocks, which surround granites. These rocks contain the same families of crystals as granites, but their resistance to erosion is minimal and their shapes are more slender than the others.
Sedimentary rocks, which are generally grouped into two large families, namely basic rocks (limestone, dolomite, calc schist, carniole), and acidic rocks (stoneware, clayey schist, quartzite).

 

Mont Blanc quartz

Millions of years later (as already mentioned, it has still been evolving for 70 million years) the Alpine orogeny raised this granite intrusion creating fractures in which cracks and fissures opened. The formation of mineral crystals is the result of mineralized water being injected into these fissures. The growth process of the quartzes in the alpine fissures is not yet fully understood. For this reason, Mont Blanc is also known as a mineralogical locality and a large quantity of different minerals comes from its slopes, above all rock quartz and pink fluorite considered the best. As evidence of a past of exploitation of mineral resources in the massif, on the Italian side there are still two ancient mines of silver galena and blende, abandoned for some time now. One was already known in antiquity with the name of Trou des Romains and it really seems that its exploitation began in Roman times; the other, the Miage mine was abandoned in the 19th century, and is positioned at an altitude of 3,500 m, with the entrance directly from the rock face, at the foot of the Tête Carrée.

At 3,462 m above sea level, in Punta Helbronner, on the Terrace of the Glaciers there is a permanent exhibition of crystals from the Massif and among the 150 minerals on display you can admire the most particular varieties of rock quartz, hyaline and smoky morions ; the Vesuvius and the garnets found near Châtillon, the minerals of the ancient mines, among which the samples of native gold of Brusson and of violano of Saint Marcel, the only locality of discovery in the world. Jacques Balmat's knowledge of the massif was also due to the fact that he himself was a crystal seeker (as well as a chamois hunter), and if quartz and fluorite are the sovereign minerals of Mont Blanc, many can be found still others such as: Adularia (KAlSi3O8); Ankerite (Ca(Fe++, Mg, Mn) (CO3)2); beryl (Be3Al2Si6O18); Calcite (CaCO3); Dolomite (MgCa(CO3)2); Hematite (Fe2O3); fluorapatite (Ca5(PO4)3F); Galena (PbS); Siderite (FeCO3); Titanite (CaTiSiO5); the Epidote (Ca2(Fe+++, Al)3(SiO4)3(OH)).

 

Climate

Mont Blanc has a mild climate, it is 240 km from the Mediterranean Sea and 620 km from the Atlantic Ocean. In the massif where it is found, the climate is semi-continental and is conditioned by the humid winds coming from the Atlantic. Once they reach the massif, these tend to cool along the watershed and on the heads of the valleys, causing rainfall conditions at low altitudes, with a maximum of rainfall in July and August and a minimum in January and February. Weather conditions can change very quickly with heavy snowfalls, sudden fogs and freezing winds. Above approximately 3,000 m, precipitation in autumn and spring falls mainly as snow, rarely as freezing rain, and is more frequent in summer than in winter due to the decreased humidity of the cold air in winter.

Above 3,800 m, all precipitation is snowy and guarantees a strong accumulation of snow on the glaciers that surround the mountain. These precipitations often turn into real snowstorms, especially on the highest altitudes and on the summit where during these storms the accumulations of fresh snow reach up to 4 meters thick. The number of days of snowfall above 3500 m can be estimated at between 150 and 160, with a rainfall intensity on the summit of about 20 cm of snow (corresponding to about 20 mm of water) per day. During the year, between 15 June and 15 July, around the summer solstice, a sort of thaw can be witnessed on the summit, with maximum temperatures reaching 3 °C. The action of the sun melts the surface snow creating water which filters into the lower layers and then freezes rapidly.

In addition to the abundant snowfalls, the winds also play a decisive role in the formation and conservation of the summit ice cap. If on the one hand the dry winter winds sweep away the snow, on the other hand the humid spring winds, characterized by abundant rainfall, bring large quantities of it. On the top the wind speed can reach 150 km/h and the temperature - 40 °C. Perturbations caused by the foehn are also frequent, a warm wind that blows from Val Ferret, and in passing the buttresses of the Valle d'Aosta side it loses humidity causing heavy snowfalls at high altitudes, to descend towards the Arve valley even hotter favoring sunny days . During excursions on the mountain, the wind reinforces the sensation of cold and the perceived temperature is lower than the actual one in the surrounding environment (Windchill effect).

 

Glaciers

The Mont Blanc massif is one of the largest alpine areas covered by ice and its glaciers, 65 in all, occupy an area of 165 km². The largest are located on the French side where the slopes are less steep and exposed to the north. These include the Bossons glacier and the mer de Glace which almost reach the Chamonix valley. In the Alps, the latter is the third largest, with about 40 km² of extension, after that of Aletsch in the Bernese Alps in Switzerland and that of Gorner in Monte Rosa, also in Switzerland. On the southern side, the Italian one, there are the glaciers of Freney, Brenva, Miage, Mont Blanc, Triolet, Pré de Bar, to name a few. Among the alpine glacial landscapes, that of Val Veny is one of the most singular: two imposing frozen rivers descend from the top of the Bianco up to an altitude of 1,200 m on the bottom of the valley, barring its entrance. Continuing in the valley itself, another glacial tongue, that of the Miage glacier, breaks into the valley occupying it for its entire width for almost three kilometers in length.

Currently Mont Blanc is subjected to continuous monitoring to better know and understand what happens to the ice on the summit cap. Due to climate change and the consequent generalized increase in temperature, for some decades those of Bianco (and in general along the entire Alpine arc) have been in sharp decline, especially the smaller ones. According to data from the most recent research, in recent years there has been a particular phenomenon which considerably increases the ice sheet above 4,000 m, so much so that the top of the mountain has increased by 2.15 m and the entire summit cap by 10,000 m³ of ice. According to meteorologists, this increase is explained by the fact that in recent years the number of days characterized by westerly winds has increased, i.e. those that push oceanic perturbations very rich in humidity towards the Alps. This humidity turns into snow at high altitudes, and rain at lower altitudes.

 

Flora and fauna

In the territory on which Mont Blanc stands, the mountain slopes are steep and smoothed by glaciers, with predominantly acid soils, consequently the environment is rather poor in flora. Generally the snow persists above 2,800 m of altitude. On the western side, the first slopes are located at 3,500 m while on the opposite side they start from the Valle d'Aosta valley floors. Given the extreme conditions, the life of plant and animal species is very limited, but among the crevasses or sheltered between granite walls, some plant species manage to survive up to 4,000 m, such as the glacier buttercup. At those altitudes there are also mosses and lichens. At lower altitudes the soils often originate from calc schists or calcareous rocks and the living conditions for the plants are less extreme, while remaining characteristic of a severe mountain environment.

At these altitudes coniferous forests prevail, populated above all by spruce and larch, but locally also by stone pine and mountain pine. On the other hand, in the alpine prairie it is possible to observe many species of flowers including the showy yellow inflorescences of Hugueninia tanacetifolia, an endemic plant of the western sector of the Alps, and the Anemone narcissiflora, and again the gentian (Gentiana clusii), the well-known edelweiss , the rare yellow bellflower. In the undergrowth we can find the Venus slipper orchid (Cypripedium calceolus), the Dactylorhiza sambucina orchid, the martagon lily (Lilium martagon), the aquilegia, the violet (Viola calcarata), and the common blue gentians (Gentiana verna and Gentiana acaulis). The presence of the hybrid between the purple gentian (Gentiana purpurea) and the dotted gentian (Gentiana punctata) is interesting. Going higher you will come across shrubs such as rhododendron (Rhododendron ferrugineum) and blueberry. In the heart of the massif, at 2,175 m a.s.l. there is the highest botanical garden in Europe: the Saussurea Alpine Garden, which collects and enhances the natural species of flora characteristic of Mont Blanc.

It takes its name from the Saussurea alpina flower, named in honor of the Geneva scientist Horace-Bénédict De Saussure, promoter of the first ascent of Mont Blanc in 1786. Mammals cannot survive such difficult conditions, contrary to certain species of birds. At lower altitudes, however, the fauna is richer and more varied. The proximity of two National Parks (Gran Paradiso and Vanoise) has contributed to the maintenance and diffusion of some species that had been reduced to a few specimens. Among the mammals it is possible to meet the alpine chamois, which frequents both the alpine plains and the subalpine woods, where it is also possible to meet two large herbivores such as red deer and roe deer. The large stony grounds of the Alpine plain see the presence of the ibex, the golden eagle and its main source of food: the marmot. An animal that can be found both in the high-altitude meadows and in the valley floor is the fox. The wolf has been reported in the valley floor. [24] In the area of the massif, 184 species of birds have been observed and about 110 of these are nesters. In addition to the eagle, among the birds of prey you can spot buzzards, goshawks and kestrels.

Sometimes it is possible to observe the circular flight of the lammergeier, the bearded vulture which became extinct in the Alps at the beginning of the 20th century and has recently been reintroduced. There are also black grouse, hazel grouse (in Savoy and Valais, but no longer in Valle d'Aosta) and the raven. On the other hand, there are few species of reptiles and they are found at relatively low altitudes, among these the collared snake, while where the ground is stony and sunny, the asp can be encountered.

 

History

An ancient document edited in Latin dating back to 1091 speaks of a Rupes that in Chamonix was called Alba and Rupes Alba was a toponym of Mont Blanc, which varied many times over the centuries. In fact, there is news of the denomination of Says or Scez Blans in 1319; in 1532 by Mont Saint Bernard; Glaciales Montes in 1581; Mont Malay, Mont Malet or Montagne Maudite between 1606 and 1743, but also La Glacière, Les Glacières or Les Glassières between 1741 and 1743. Clearly visible from Geneva, it was known in this city both as Montagne Maudite and as Mont Maudit and with this name it was indicated on a geographical map concerning the territories around Lake Geneva, published in Amsterdam in 1606 by the Genevan cartographer Jacques Goulart (1580-1622), while the current name in French appeared for the first time in England in 1744 on a map published in London. At that time, the entire massif was located in the middle of the mainland possessions of the Kingdom of Sardinia and the rulers of the House of Savoy, future kings of Italy, had been its legitimate owners for centuries until the sale of Savoy to France in 1861.

 

Cartographic disparities

The geographical maps of the I.G.N - (Institut Geographique National de France) show the summit of Mont Blanc entirely in French territory, in stark contrast with the geographical maps of the I.G.M - (Military Geographical Institute of Florence), in which the border two states passes exactly over the top. A bilateral treaty concluded in 1861, still legally valid, unequivocally indicates the top as a frontier, i.e. divided in half between the two states. The report on the deportations to the border states that the border runs along the crest line of the massif, as seen from the church square of the village of Courmayeur. However, the summit of Mont Blanc is not visible from Courmayeur, because it is too deep; the crest line runs further east and further down, at the height of Mont Blanc di Courmayeur (hence the name). At the time, this record was maintained by France as the legal basis for the border, although nothing is specified in the annexation treaty. This boundary is still shown on current IGN 1:25,000 maps. The part corresponding to the Italian side is attributed to the municipality of Saint-Gervais-les-Bains.

This treaty was suspended throughout the Second World War. On 10 February 1947, with the Treaty of Paris, the French authorities decided to put an end to the suspension. The Delimitation Convention, after several changes, was then re-enacted. On the old route established in 1861, the transalpine authorities demanded four rectifications.

The most important of these concerned the Roia valley, Briga Marittima, Tenda, and three minor ones: one on the Italian side of the Colle del Monginevro, another on the Colle del Moncenisio, and then on the Piccolo San Bernardo. On the summit of Mont Blanc the frontier did not undergo any changes.

In the second half of the 19th century, on the surveys carried out by a French army cartographer, Captain J. J. Mieulet, a topographic map was published in France, which arbitrarily incorporated the peak into French territory, causing the state border to deviate from the watershed line, and thus giving rise to the differences with the maps published in Italy in the same period, differences that the official Italian cartography never recognized from the outset. According to the authors of a book that appeared years ago in Italian and French bookstores, the 1865 topographic map is a sensational historical forgery with no legal value, in contrast with the agreements signed between the two states since 1860 and reaffirmed in 1947.

In 2002, the two cartographic bodies mentioned, the respective Alpine Clubs, the border regions and the countries concerned published a shared topographic map. This new map, part of the Alps without frontiers project, goes one step further than the old maps, but still lacks clarity on the disputed peaks and the crosses marking the borders appear deliberately spaced out, even if the differences with the "I.G.N. top 25" map " of 1998 are evident. In September 2013 some French guides blocked the passage to the summit with a gate which was removed a few days later by the Italians.

Since 2017 Google Earth has been using the maps of the I.G.M. and of NATO. The latter takes the data from the Italian ones of the IGM, based on past official treaties in force and is essential at an international military level in the event of a possible dispute. The territory that goes from the Turin refuge to the highest peak of the Mont Blanc massif is under the control of the Italian authorities. With the current climatic upheavals, the Italian Civil Protection has highlighted the need for a clarification between the two administrations in order to avoid misunderstandings on the responsibilities regarding the surveillance of the glacier on the watershed whose waters, in the event of melting, would totally involve the Italian territory.

 

Military schools

At the end of the 19th century, special units trained for mountain warfare were created in the nations of the Alpine arc. Mountaineering thus became part of military preparation, together with the use of skis. On 9 January 1934, the Military School of Mountaineering was established in Aosta, with branches in La Thuile and Courmayeur. The first commander of the school was Lieutenant Colonel Luigi Masini. France had already equipped itself in 1932 with the l'ècole de Haute Montagne (E.H.M) based in Chamonix. The grandiose scenario of the Bianco group was then the scene of the spectacular exercises of the military schools of the two countries, with maneuvers at high altitude by specialized units. The best names in national mountaineering and skiing flocked from the Italian Alpine valleys to the Aosta school, which had become the University of mountaineering. In short, enterprises were organized and completed which aroused great admiration at the time.

On 22 June 1935, more than 200 pupils from the Scuola alpieri took a solemn oath of loyalty to the homeland and to the King on the summit of Mont Blanc, climbing it by various routes, some of which were among the most demanding. The following year, 600 fully armed men crossed the chain of the Grandes Murailles, from Valpelline to Valtournanche. In 1937 an impressive high-altitude exercise engaged the entire Duca degli Abruzzi battalion (500 men) who occupied all the border posts with France to climb, by different routes, to the summit of the Roof of the Alps. In 1938 it was the turn of the specialized French troops who met on Mont Blanc on 14 July.

In just a few years, the Military School of Mountaineering of Aosta became famous and known on an international level. Subsequently, relatively precisely to Mont Blanc, the Mont Blanc Autonomous Department was established, made up of the best elements of the Alpine troops. The task of the department (corresponding in terms of staff to a company) was to guard the Bianco area from Colle della Seigne to Col Ferret. To better organize it, it was divided into three sides led by famous names in Italian mountaineering such as Giusto Gervasutti (the Miage), Renato Chabod (the Giant) and Emanuele Andreis (the Ferret). From the outset, the school participated in competitive events in the field of winter sports and won the Olympic military patrol competition in 1936 in Garmisch. In the three-year period 1935-1937 he also won the Mezzalama Trophy for ski mountaineering.

 

The Battles of Mont Blanc

During the Second World War, Mont Blanc became the highest altitude battlefield in Europe. First the Torino refuge (3375 m), then the col du Midi (3564 m) were the scene of bloody clashes between German soldiers and French and Italian partisans. Even earlier, in 1940, Benito Mussolini, until then non-belligerent, convinced that the conflict was ending, declared war on France. On 10 June 1940, the 5th Alpine Regiment and the Duke of Abruzzi Battalion launched the attack starting from the slopes of Mont Blanc, in Val Veny, towards the Seigne pass, meeting strong resistance across the border in the French fortifications at Sélonges in Val de Glaciers.

The hostilities on the western front did not last long and 14 days later, with the armistice of 24 June 1940, operations stopped, preventing further Italian advances. Four years later, after the Allied landings in Normandy and in Provence in August 1944, the Germans (Wehrmacht) began their retreat towards Germany going up the Rhone valley pursued by the Americans of General Alexander Patch's 7th Army and by the French by General Jean de Lattre de Tassigny. The Americans ensured supplies of food and weapons to the French Resistance. Containers full of rifles, machine guns, pistols, bombs, bazookas, grenades and ammunition of all kinds rained down from the sky in Savoy. On 13 August, the command of the free French forces asked for the support of the Aosta Valley Resistance for the liberation of Savoy.

After heavy fighting the garrison of Chamonix surrendered on 17 August. Two months later, in October, the Mont Blanc battalion was created in France to defend the Massif, made up of three companies into which the formations of partisans from the upper Arve Valley, guides from Chamonix, ski instructors and guides from the C.A.F. (Club Alpin Français). Their task was to occupy and guard the high-altitude shelters. A section of S.E.S (Section d'Eclaireurs-Skieurs), i.e. a section of ski explorers from the body of French Alpine Hunters under the command of Lieutenant Jacques Rachel, was sent to the Simond refuge, at the col du Midi.

 

The battle at the Turin refuge

Taking advantage of the lack of German presence on the Massif, the Alpine explorers occupied the Turin refuge, on the Colle del Gigante on the Italian side. From that position they could see what was happening in the valley floor, checking the movements of the opposite front which in that period had stabilized on the Piccolo San Bernardo. The Germans, who had become aware of their presence, planned an attack to neutralize them. On 2 October 1944, a patrol made up of an officer and eight Gebirgsjäger (German Alpine hunters) climbed the Colle del Gigante in the night, waiting for the right moment to attack.

After a blizzard that was raging in the meantime, around 10:30 they unexpectedly launched a violent attack against the occupants of the refuge who defended themselves strenuously before surrendering. In the battle, three French partisans and one Italian lost their lives, the others were taken prisoner and taken to the valley. The shelter was then damaged to make it unusable by the Resistance. Twenty-five days after the battle, on 27 October, Sandro Pertini, the future president of the Republic, returning to Italy after his exile, spent the night in the Turin refuge half-destroyed in that action. The next day the Aosta Valley partisans accompanied him towards areas not controlled by the Germans.

 

The battle at the Col du Midi

Although the winter of 1944-1945 had been very harsh and with an uninterrupted succession of blizzards on Mont Blanc, French explorers often ventured into the Italian border to control enemy movements and prevent any attacks. The Germans, aware of this continuous surveillance, decided to occupy the watershed up to the Simond refuge on the col du Midi and neutralize the cableway. The German command thus planned the operation Himmelfahrt ("ascension into heaven"), under the command of Oberleutenant Hengster, an expert mountaineer, who could count on 176 men, including officers and soldiers of the troops chosen for battles at high altitudes. Their movements and exercises in the weeks preceding the attack were closely monitored by the Aosta Valley Resistance and timely reported both to the Allies and by radio in Aosta Valley patois to the French Resistance. On 16 February 1945 the Germans went up to the Turin refuge but were spotted by French scouts on the same day. The next day the attack started.

The Germans descended through the Vallée Blanche on their way to the Simond refuge. Their plan envisaged a central attack supported by the bulk of the forces while two detachments invested the col du Rognon on the right and the rocks of Tacul on the left. Lieutenant Rachel didn't want to be surprised and decided to go to meet the enemy with whom he already made contact during the night. After a violent battle, the French decided to retreat by climbing the crest of the Rognon, but their position soon proved to be indefensible. They withdrew again crossing the Vallée Blanche under fire from a German machine gun. They reached the remaining forces at the col du Midi and perched, returning to the German fire. The Germans' radio was out of order so they had no way to use the artillery as their position became increasingly critical. They decided to retreat while a French plane suddenly appeared and threw grenades from above. They withdrew and took up defense on the Colle del Gigante. The surprise attack on the Simond refuge had failed. The Germans suffered the loss of nine soldiers while the French counted only one loss.

At that point the Transalpines strengthened their garrison on the Col du Midi by bringing in machine guns and two mountain batteries. With these howitzers, without being able to visualize it, they tried to hit the cable car on Mont Fréty, the one that connected the hill with the valley floor, but in vain. Instead, they were the target of the German howitzers which from Mount Fréty fired salvos on the Simond refuge and on the cableway. They managed to hit both of them, breaking a support cable of the cable car and destroying the shelter. This time it was an artillery battle. The French resumed shooting the following day, aided by a reconnaissance plane which gave radio indications of the success of the shots. A shot hit the support pylon of the cableway putting it out of action.

 

The Vincendon-Henry case

The Vincendon Henry case was a tragic mountaineering affair involving two young climbers: Jean Vincendon, a 24-year-old Parisian, and François Henry, 22, from Brussels. The two left on 22 December 1956 to spend New Year's Eve on the Brenva spur, a majestic rocky summit on the east side of Mont Blanc. During the approach route they meet Walter Bonatti and Silvano Gheser who were heading towards the winter ascent of the Via della Poire. The ascent of both teams began at 4 am on Christmas morning, the ideal time for Vincendon and Henry's itinerary, but already too late for what Bonatti and Gheser would have had to do. In fact, after a few hours of sunshine the conditions of the ice worsened and the Bonatti roped party was forced to descend on the Brenva and follow the Vincendon roped party.

However, the four climbers were caught in a violent storm which forced them into a dramatic 18-hour bivouac at an altitude of 4,100 m. Bonatti and Gheser managed to reach the Gonella refuge where they were rescued on 30 December by the mountain guides Gigi Panei, Sergio Viotto, Cesare Gex and Albino Pennard. Gheser, affected by severe frostbite, will have some toes of both feet and one hand amputated. Vincendon and Henry, who opted to go directly to Chamonix, died after five days of cold at an altitude of 4000 m while waiting for the rescue teams, blocked by bad weather, to pick them up (they were still alive by a helicopter which, however, fell on the glacier) . The bodies of the two young climbers were only recovered in March 1957. The tragedy will mark the establishment of the PGHM, the French mountain rescue military group (Peloton spécialisé de haute montagne).

 

The Tragedy of Freney

In July 1961, one of the most dramatic events in the history of mountaineering took place on the Italian side of Mont Blanc. The Freney Central Pylon was a much sought-after destination for climbers from all over the world, one of the last not yet conquered. Its red granite wall was very difficult to climb and for many even considered impossible. Walter Bonatti and Pierre Mazeaud, both already legends of mountaineering, met on Sunday 9 July at the Bivouac della Fourche heading towards the same objective and decided to join forces to attempt the climb together.

With them Andrea Oggioni, Roberto Gallieni, Pierre Kohlmann, Robert Guillaume and Antoine Vieille, all known and expert rock climbers. The weather was good and stable conditions were expected. After a day and a half of approaching, they reached the Chandelle, i.e. the summit cusp of the pylon, at an altitude of 4,500 m. When there were 120 m to go to the end of the climb, the roped party was hit by a sudden blizzard which blocked them on the wall. It was 2 in the afternoon on Tuesday 11 July: the weather had changed quickly as often happens on Mont Blanc. It was impossible to continue, we had to retreat to find shelter in the Gamba refuge (now the Monzino refuge). The alpine guides Gigi Panei and Alberto Tassotti were the first to set out in search of the two Bonatti-Mazeaud roped parties and to understand the desperate situation of the seven mountaineers, after having discovered their traces at the Bivacco della Fourche. Journalists and onlookers flocked to Courmayeur and all of Italy followed the development of the tragedy, told hour by hour on live television and radio by journalists Emilio Fede and Andrea Boscione. Panei, after having read Bonatti's message in the refuge's blue book ("Going to the Central Pillar of Freney"), rushed to the headquarters of the Alpine Guides Society of Courmayeur, avoided Emilio Fede who wanted to interview him, and went straight to the councilor of the Toni Gobbi Guides to give him the news. Rescue immediately left, coordinated by Ulisse Brunod to track down the mountaineers who had now been stranded for three days.

On the morning of 15 July, exhausted by cold and fatigue, Antoine Vieille lost his life at Rochers Gruber, after 5 bivouacs on the wall. Robert Guillaume, in the evening of the same day, fell into a crevasse of the Freney glacier. In the night between Saturday and Sunday 16 July it was Andrea Oggioni who lost his life on the Innominata hill just three quarters of an hour from the Gamba refuge. The survivors slowly approached safety, but just before reaching the refuge Pierre Kohlmann collapsed lifeless in the snow. At 3 in the morning on Sunday, Walter Bonatti and Gallieni finally reached the Gamba refuge where they found the men of the rescue teams. Soon after they caught up with Mazeaud left behind, saving him.

The plane crashes

On the Italian side of the Bianco, characterized by rugged walls falling within the municipal area of Courmayeur, there have been several plane crashes which have caused the loss of many human lives. In their descent towards the valley floor, the glaciers carry evidence of those tragedies by returning parts of nacelles, remains of engines and propellers, human remains and clothing which together with other finds help to reconstruct what happened. On November 1, 1946, an American B17 Flying Fortress bomber exploded on the southwest ridge of the Aiguille des Glaciers in upper Val Veny. It was a four-engined 23 m long and 32 m wingspan, with serial number 43-39338 belonging to the 61st Troop Carrier Group stationed in Italy. It departed from Naples and was bound for London with eight passengers on board, including three officers: two lieutenant colonels and a major. The causes have never been ascertained but bad weather conditions most likely played a decisive role. The first wrecks together with human remains were discovered in 1970 near the Elisabetta refuge, transported by the Estelette glacier. Later, on the French side, Glacier des Glaciers yielded more remains of American soldier crew members.

Still on the east side, just below the peak where the Mont Blanc Glacier originates, between the Rocher de la Tournette and the Courmayeur Mont Blanc, two Air India planes crashed tragically sixteen years apart from each other. On November 3, 1950, the Malabar Princess, a four-engine Lockheed Constellation L 749 operating on the Bombay - London line, was preparing to face the descent towards Geneva where an intermediate stop was scheduled. The aircraft was piloted by the English commander Alain R. Saint who knew the route well. The last radio contact occurred at 10:43, when the control tower of Grenoble received a communication from the commander who reported that he was above the vertical of Voiron at an altitude of 4,700 m. From then on, contact was lost. Bad weather conditions slowed down the search. A violent blizzard lasted for two days preventing rescue workers from approaching the disaster site.

On 5 November, with the weather improving, a Swiss plane sighted a wing of the plane stuck in the ice on the Italian side. The plane had crashed at an altitude of 4,677 m, just below the summit of Mont Blanc near the Rocher de la Tournette, the Grande Bosse and the Petite Bosse (Bosses du Dromadaire) about 1,000 m from the Vallot hut. The fresh snow in November complicated the arrival of rescue workers by increasing the possibility of avalanches and concealing crevasses. One of these was fatal for René Payot, the Chamonix guide, who lost his life 100 meters from the place where in 1936, by tragic coincidence of fate, his brother disappeared overwhelmed by an avalanche. None of the 48 passengers (40 + 8 crew members) survived and the exact causes were never ascertained. In 2008, an English student, following the glaciologist Tim Reyd who was studying the Miage glacier in Val Veny, after having entered the crevasses for 2 km, found a blue container emerging from the ice, inside which were kept 75 letters from 1950 all headed for America. They were part of the cargo of the Malabar Princess which carried trunks of mail in addition to passengers.

On 15 September 1986 on the French side, on the Bosson glacier at an altitude of 1,900 m, one of the engines resurfaced among the ice, and a second was found on 22 September 2008, at 2,000 m, again on the same glacier. On 24 January 1966 the same fate was reserved for the Boeing 707 Kangchenjunga, flying on the Bombay - New York route with intermediate stops in Beirut, Geneva and London. The plane, followed by Milan's radars as it was preparing to fly over Mont Blanc, suddenly disappeared from the screens. Using helicopters, rescuers quickly reached the disaster site. Of the 117 passengers, none survived. Among the victims was the nuclear physicist Homi Jehangir Bhabha, father of the Indian atomic bomb. In its cargo, the plane was carrying 200 monkeys destined for a medical laboratory. According to the testimonies of the rescuers, some survived the crash. In the summer of 1985, two Piedmontese mountaineers on their ascent to Mont Blanc came across the tail of Kangchenjunga which, under a shimmering veil of ice, revealed the silhouette of a belly dancer, symbol of the airline. At the time of the plane's disappearance, it was said that there was a maharaja on board and it was speculated that the hold of the Boeing contained a large amount of jewels and that the following summer, quite a few ventured into the ice in a sort of hunt to treasure. Both planes crashed almost on top and wreckage was strewn everywhere even across the border into French territory. As the ice slowly flows downstream, it returns pieces of cockpit and wings, always keeping alive the memory of those tragedies.

 

Ascents

First ascent

After a few attempts at reconnaissance carried out together with the Aosta Valley guide Jean-Laurent Jordaney starting in 1784, the first ascent was made by Jacques Balmat (24 years old, crystal seeker) and Michel Gabriel Paccard (29 years old, doctor), both of Chamonix. They were urged to the enterprise by the scientist Horace-Bénédict De Saussure, who used to observe the summit from his house in Geneva. It was De Saussure who in 1760 promised a prize of three guineas to anyone who climbed it. 26 years passed before his dream came true. The enterprise had been preceded by some reconnaissance, in one of which Balmat got lost and was forced to spend the night in the snow, an eventuality then considered extremely dangerous, such as to leave no hope, due to the temperatures.

The ascent was constantly followed with a telescope by the Prussian baron Adolf Von Gersdorff who, from a hillock above the town of Chamonix, followed the movements step by step, noting them in a diary. According to reports, at a certain moment of the ascent Balmat wanted to go back because he was deeply worried about the health of his few days old daughter. Paccard, who was unaware of this, persuaded him to continue. They reached the summit on 8 August 1786 at 18:23, passing between the Rochers Rouges, and it was Paccard who was the first to trample the snow on the summit fourteen and a half hours after setting out. They remained there for 34 minutes, the time needed to carry out measurements of the atmospheric pressure, with Torricelli's barometer, confirming the theories of Florin Perier (Blaise Pascal's brother-in-law), of a century earlier, on the exponential reduction of the pressure as the altitude. The measurements also served for the first rough measurement of the height of the summit, which, however, was significantly overestimated. At 18:57 they set off again and after four hours they reached the hut from which they had left that same morning. They spent the night there and returned to Chamonix at 8 in the morning where Balmat learned the news of the death of his little daughter the day before, confirming his bad forebodings.

After paying the promised prize, De Saussure also wanted to reach the top. It was Balmat who organized the expedition and prepared two shelters for overnight stays. On August 13, 1787, accompanied by his personal servant and 18 guides carrying food, drink, ladders, a bed, a stove and a scientific laboratory (hygrometers, barometers, thermometers), the Genevan scientist fulfilled his dream. Even the king of Sardinia, Vittorio Amedeo III of Savoy, proud of his subject's feat, awarded Balmat a cash prize and the right to postpone the name «called Mont Blanc» to the name. Paccard, due to jealousy and envy, was soon forgotten by all. It was the Genevan writer Marc Théodore Bourrit who defamed and discredited him and insisted on giving his partner all the credit for the enterprise, even though Balmat himself, in a sworn statement published in the Lausanne Gazette, said the opposite. The report that Paccard prepared for the press in defense of him was never published and all was in vain against the defamation campaign. For a long time, for the scientific world, de Saussure will be the first conqueror of Mont Blanc with Balmat as guide. Only after the discovery of the diary of Baron A. Von Gersdorff at the beginning of the twentieth century and then of other documents, the primacy will be definitively recognized to Paccard.

 

First winter ascent

The first ever winter ascent was made on 31 January 1876 by Miss Isabella Straton, Jean Charlet, Sylvain Couttet, via the Grand Mulets and the Bosses ridge. The first winter crossing was made on 5 January 1887 by Alessandro, Corradino, Erminio and Vittorio Sella, Émile Rey, Jean Joseph, Baptiste and Daniel Maquignaz, and two porters. They climbed the Rocher de la Tournette route and descended from the Grand Mulets in a day.

 

First female ascent

The first woman to reach the top was Marie Paradis on July 14, 1808 accompanied by her 14-year-old son Gédéon and Jacques Balmat as her guide. Her feat earned her the nickname of Marie du Mont Blanc. The second female ascent was instead made by Henriette d'Angeville on 4 September 1838, while the first woman to make the climb during the winter period was Isabella Straton on 31 January 1876 together with Jean Charlet, Sylvain Couttet and Michel Balmat. In 1929, Marguette Bouvier was responsible for the first ski descent made by a woman.

 

Ascent and descent speed record

The first ascent and descent record from Courmayeur was set in 1995 in 6 hours 45 minutes and 24 seconds by the Italian Fabio Meraldi. The route has a development of about 52 kilometers and a height difference of about 3,800 meters. This record was broken on 16 July 2015 by the Italian mountain running athlete Marco De Gasperi, who completed the same route as Meraldi (the Italian Way, which starts from Courmayeur and continues to the Piton des Italien) in 6 hours 43 minutes and 52 seconds.
The ascent and descent record from Chamonix was set on 11 July 2013 in 4 hours 57 minutes and 40 seconds by the Spaniard Kílian Jornet i Burgada. Leaving the Chamonix church at 4.46am, Jornet spent 3 hours and 33 minutes on the ascent and 1 hour and 24 minutes on the descent. The route has a development of 30 kilometers and a height difference of 3,800 meters. Jornet lowered by 13 minutes the previous record set by the Swiss Pierre-André Gobet which had stood for 23 years: on 21 July 1990 Gobet had completed the ascent and descent in 5 hours 10 minutes and 14 seconds.
The ascent and descent record on skis from Chamonix was set on 14 May 2013 in 5 hours and 5 minutes by the Frenchman Mathéo Jacquemoud. Jacquemoud lowered by 10 minutes the previous record set by Stéphane Brosse and Pierre Gignoux, who on 30 May 2003 had ascended and descended Chamonix on skis, in tandem, in 5 hours, 15 minutes and 47 seconds.
On 18 September 2012 the Spaniard Kílian Jornet i Burgada made the solo crossing of Mont Blanc via the Innominata ridge in 8 hours and 42 minutes. Leaving Courmayeur at 3:53, he reached the summit of Mont Blanc in 6 hours and 17 minutes and then reached Chamonix in 2 hours and 19 minutes. The route has a development of 42 kilometres.

Economy and infrastructure

Tourism

With 15 million tourists a year, Mont Blanc is one of the most visited places in the Alps. Since the past centuries, the attraction generated by the beauty of the mountains and valleys that surround it has always been remarkable. Beginning in 1741, the stories of the English aristocrats William Windham and Richard Pococke about their journey on the Sea of Ice spread throughout Europe arousing great curiosity. In a short time, wealthy tourists, mostly English, arrived in the remote mountain towns of the Kingdom of Sardinia to admire the mysterious glaciers and untouched mountain peaks. Those mountain villages are considered to be one of the places where tourism itself was born. First winter tourism and then later also summer tourism as a direct consequence of the unexpected race to conquer the impervious and untouched peaks. The inauguration of the first hotel in Chamonix in 1770 initiated the development of the hotel industry. Luxury hotels followed and together with Courmayeur they became one of the most sought-after holiday resorts, frequented by nobles, writers, scientists and the first mountaineers, even before tourism itself became a mass phenomenon.

Alpine guides

The environment of Mont Blanc, due to its vastness and its historical importance, being a destination for explorers and mountaineers since the end of the eighteenth century, gave a great impulse to the birth of the profession of mountain guide. Here the first guide companies were born:

the Compagnie des guides de Chamonix, born on 24 July 1821, was the first company of guides in the world. On May 9, 1823, through a manifesto of the Turin Chamber of Deputies, the King of Sardinia, Carlo Felice of Savoy, made its creation official.
the Courmayeur Alpine Guide Society, born in 1850, was the first Italian alpine guide company and the second in the world after that of Chamonix. Its historic headquarters became a museum in 1929: the Duca degli Abruzzi Alpine Museum which houses important relics from expeditions not only to the Mont Blanc massif but also to Tibet, the Himalayas, Africa and India. The guides distinguished themselves during the first attempts made to reach the summit of Mont Blanc starting from Courmayeur, but also during the ascents of the Matterhorn where they were protagonists with Jean-Antoine Carrel and Jean-Joseph Maquignaz.

 

The Glacier Cableway

In La Palud, near Courmayeur, the route of the Mont Blanc cable car begins, designed and conceived by the engineer Dino Lora Totino. In just under an hour you can reach Chamonix, in France, completely bypassing the chain of the Alps. Initially conceived for predominantly military purposes, it was inaugurated in the summer of 1947 and until 2015 was divided into six different sections: from La Palud you reach the Pavillon di Monte Frety at an altitude of 2,175 m; continue to arrive at the Torino refuge at Colle del Gigante at an altitude of 3,330 m (almost 2,000 meters in eleven minutes); continue from Colle del Gigante to Punta Helbronner at an altitude of 3,462 m from where you can enjoy a view over the entire Alpine arc: from the top of Mont Blanc to the Dente del Gigante, to the famous "4,000" in Europe such as the Matterhorn , Monte Rosa, Grivola, Gran Paradiso. Continuing from Punta Helbronner we continue towards the Aiguille du Midi, the highest point at an altitude of 3,842m; from the Aiguille du Midi it is possible to descend to Plan de L'Aiguille, at 2,137 m, to finally arrive in Chamonix. The cable car was completed in the sixties, and features some unique technical solutions, such as the suspended pylon.

Renovation works have been carried out on the entire Italian section since 2011 with the construction of a new departure station and the elimination of the one at the Rifugio Torino, as well as the replacement of the cabins with more modern and safer structures. The works started on April 10, 2012 and ended on May 29, 2015. On May 30, 2015 the renovated cable car reopened to the public with the new name of SkyWay Monte Bianco. The second section of the new cable car leads directly from the Pavillon di Monte Frety to Punta Helbronner. In this way the intermediate stage at the Torino refuge is avoided, so the entire traverse is now divided into only five sections, and no longer six as previously.

 

The protection of Mont Blanc

The influx of so many tourists, although an asset, is in itself a danger to the environment. The Aosta Valley, Savoyard and Valais communities, with the help of the regions and states concerned, with a cross-border approach to the problems relating to the protection and enhancement of the territory have found an agreement to give life to the Spazio Monte Bianco project. This cooperation initiative involves 35 municipalities between Savoy, Upper Savoy, Valle d'Aosta and Valais and is coordinated by the Mont Blanc Cross-Border Conference. Under the presidency of one of the ministers of the environment, the Conference brings together 5 representatives of the State and of the territorial authorities for each nation. Overall, the Mont Blanc Area occupies an area of approximately 2,800 km² and includes 35 municipalities: 15 in Savoy and Upper Savoy, 5 in Valle d'Aosta and 15 in Valais. In total, the entire area has about 100,000 inhabitants. The Mont Blanc massif site was recently nominated by UNESCO to be classified as a World Heritage Site.

 

The Mont Blanc tunnel

The Mont Blanc tunnel is a motorway tunnel that connects Courmayeur in Valle d'Aosta (Italy) to Chamonix-Mont-Blanc in Haute-Savoie (France). It was built jointly between Italy and France. The construction work began in 1957 and ended in 1965, the year of the opening. It consists of a single tunnel with two-way traffic and is one of the major transalpine transport routes. Its length is 11.6 km and the longest part remains in French territory: 7,640 m, with 3,960 m in Italy. The altitude is 1,381 m on the Italian side, at the foot of the Brenva glacier, while it reaches 1,395 m in the middle of the gallery, to then drop to 1,271 m on the French side, at the foot of the Bossons glacier. The road surface of the tunnel is not horizontal, but concave in shape to facilitate the outflow of water.

With respect to the border, the tunnel passes exactly under the vertical (l'aplomb) of the Aiguille du Midi, where the thickness of the granite cover reaches 2,480 m, a record size for motorway and railway tunnels. Its height is 4.35m and its width 8m (2x3.5m for the aisles, and 2x0.5m for side passage). The doubling of the tunnel, already planned, was never carried out due to the opposition of the inhabitants of the valleys concerned, worried about an excessive increase in the circulation of trucks and the consequent pollution. The tunnel was inaugurated on 19 July 1965 and its management, on an equal basis, is divided between two concessionary companies: the Italian S.I.T.M.B (Società Italiana per il Tunnel del Monte Bianco), created on 1 September 1957 and the French ATMB ( Autoroutes et tunnels du Mont-Blanc), created on 30 April 1958. For a long time it remained the longest motorway tunnel in the world. From 1965 to 2004, 45 million vehicles passed through it with an average of 3,083 vehicles per day.

 

The laboratories of Mont Blanc

Another lesser known aspect of Mont Blanc is that of study and research. In fact, inside the mountain there are very important laboratories managed by the Institute of Physics of Interplanetary Space of the CNR (National Research Center) of Turin, which works in collaboration with the INFN (National Institute of Nuclear Physics) of Frascati (Rome ) and the University of Milan. In these laboratories research on cosmic rays is conducted and they served as a prototype for two other famous laboratories: the one under the Gran Sasso, in the central Apennines, built later, and the laboratory managed by CERN in Geneva which studies elementary particles.

In the past, attempts were made to build some on top as well. In 1891, the French scientist Pierre Janssen worked to build an observation center on the summit, in the hope of optimally carrying out measurements and research on the solar spectrum. The lack of solid foundations and the continuous movements of the ice on the summit cap led scientists to abandon it in 1906, as it had become unsafe. In 1890, on the French side, at an altitude of 4,365 m, the botanist and meteorologist Joseph Vallot built a laboratory chalet with a multidisciplinary vocation, including astronomy: the Vallot Observatory.

 

Curiosity

In the summer of 2020 during the project: "FivePeaks", Andrea Lanfri and Massimo Coda, two disabled Italian mountaineers, who ironically define themselves as "two men and one leg" and count three prostheses in two, conquered the summit of Mont Blanc in total autonomy, going up from via Ratti (normal Italian). They are the first two disabled athletes to attempt and succeed in the enterprise.

 

In mass culture

With the birth of mountaineering, the mountain literary genre was born. The clamor aroused by the conquest of Mont Blanc attracted poets, writers and painters to its valleys at the beginning of the 19th century. From England and northern Europe, aristocrats traveling on the Grand Tour visited the Alpine mountains, while great mountaineers such as Albert Frederick Mummery, William Auguste Coolidge and Edward Whymper climbed peak after peak, later writing books in which they recounted their exploits. The English romantics fell in love with the Alps. Samuel Taylor Coleridge wrote a hymn to Mont Blanc and Percy Bysshe Shelley, after admiring the mountain, said: «I didn't know, I had never imagined before what mountains were» and wrote Mont Blanc, one of the his most famous poems.
