Devil’s Lake, Wisconsin

Devil’s Lake

Location: Sauk County Map

 

Devil’s Lake (Tee Wakącąk or Te Wakącąk / Sacred Lake or Spirit Lake) in Sauk County, Wisconsin, is a dramatic endorheic (or cryptorheic) lake nestled in a gorge within the Baraboo Range, now the centerpiece of Devil’s Lake State Park.
It attracts over a million visitors annually for its quartzite bluffs, hiking, climbing, swimming, boating, and scenic beauty. Its history spans billions of years geologically and thousands of years of human presence, marked by Indigenous reverence, 19th-century tourism and resource extraction, and 20th-century conservation.

 

Landmarks

The Baraboo Range’s quartzite bluffs are among North America’s oldest exposed rocks, dating back ~1.6–1.7 billion years. Ancient river sands deposited in shallow seas compacted into sandstone, then metamorphosed under heat and pressure into hard quartzite. Tectonic forces uplifted the ranges, erosion carved valleys and gorges, and later seas deposited more sediments before rivers re-exposed the bluffs.
During the last Ice Age (~12,000–15,000 years ago), the Wisconsin Glacier stopped short of fully covering the area, depositing terminal moraines that dammed an ancient river valley at both ends, creating Devil’s Lake. The lake is roughly rectangular (about 1 mile north-south, 0.5 mile east-west), 40–50 feet deep on average, with sandy glacial bottoms and large talus (scree) slopes at the base of the cliffs. Features like ripple marks, potholes, and unconformities (gaps in rock layers) are visible along trails.

Major Landmarks and Rock Formations
Balanced Rock: One of the park’s most iconic sights, this large quartzite boulder appears precariously perched on a ledge high on the East Bluff, overlooking the lake. It’s reachable via a short but rewarding trail (part of longer loops) and offers stunning panoramic views. Glacial and erosional forces shaped it.

Devil’s Doorway: A dramatic natural rock arch or window formation on the East Bluff, formed by erosion and frost wedging. It provides breathtaking views of the lake and surrounding hills, especially striking in fall foliage or misty conditions. It’s a popular short hike destination.

Talus Slopes and Cliffs: Massive piles of broken quartzite boulders at the base of the bluffs on three sides of the lake, created by freeze-thaw cycles. These are prominent features for hikers and climbers.

Parfrey’s Glen State Natural Area (adjacent but managed with the park): A deep, scenic gorge with steep cliffs, a mountain-like stream, waterfall elements, and unique Cambrian sandstone formations (different from the main quartzite). It’s Wisconsin’s first State Natural Area, offering a lush, shaded hike contrasting the open bluffs.

Other notable features include Elephant Cave, potholes, ripple marks in the rock, and various overlooks like Prospect Point on the West Bluff (highest point, ~500 ft above the lake).

Cultural and Historical Sites
Effigy Mounds: Ancient Native American burial and ceremonial mounds in animal shapes (e.g., lynx, sparrow) and linear forms, located near the Nature Center and elsewhere. These are culturally significant; respect them and learn more at park programs.
Civilian Conservation Corps (CCC) Structures: Trails, buildings, benches, and other infrastructure built in the 1930s by CCC workers. The Nature Center and many trails reflect this legacy.
Historic Resorts and Development: In the late 19th/early 20th century, the area had hotels, summer homes (including Ringling Brothers connections), and recreation facilities. Most were removed as the park was established in 1911, restoring its natural character.

Recreational Highlights Tied to Landmarks
The park offers ~29 miles of hiking trails (easy lakeside paths like Tumbled Rocks Trail to strenuous bluff climbs), rock climbing on quartzite cliffs (a Midwest premier spot), swimming at two sandy beaches, boating/kayaking, fishing, birdwatching (over 200 species), and winter activities.
Popular hikes combine landmarks: East Bluff Trail (to Devil’s Doorway and Balanced Rock), West Bluff Trail (cliff-edge views), and loops around the lake.
The Nature Center provides exhibits on geology, history, and wildlife, plus programs.
Tips: The park gets very crowded on weekends/holidays (May–October); arrive early. Vehicle admission sticker required. Stay on trails for safety and to protect fragile features.

 

Hiking trails

The park is part of the Ice Age National Scenic Trail, which passes through for about 13.7 miles, highlighting glacial geology like moraines, kettles, talus slopes, and potholes. Trails are well-marked but can be busy in summer; many involve stone steps, uneven rocky terrain, and potential drop-offs—proper footwear is essential. About 1.5 miles are accessible (e.g., parts of Tumbled Rocks and Grottoes).

Popular Loops and Iconic Hikes

Geography and Geology

Location and Overview
The lake lies in a narrow gorge within the Baraboo Hills (part of the Baraboo Range), a canoe-shaped geological structure. The park itself spans 9,217 acres (the largest in Wisconsin), with the lake covering about 360–374 acres. It is roughly rectangular: a little over a mile long (north-south) and about half a mile wide (east-west). Maximum depth is around 40–50 feet (some sources note up to ~47 feet), with the water surface at an elevation of roughly 961 feet (lake level varies). The bluffs rise dramatically 500 feet above the lake in places.

Geological History (Over 1.7 Billion Years)
The geography results from a multi-stage process involving ancient seas, mountain-building, erosion, and glaciation:

Precambrian Origins (~1.6–1.7 billion years ago): The core of the Baraboo Range consists of highly resistant Baraboo quartzite, formed from sand deposited in shallow seas, later metamorphosed under heat and pressure into a hard, non-porous rock. This makes the bluffs among the oldest exposed rock outcrops in North America.
Folding and Erosion: Tectonic forces buckled the quartzite into the North and South Ranges, creating a depression (Baraboo Valley). Softer rocks eroded away, forming gorges. Ancient rivers carved gaps, including the one now occupied by the lake.
Seas and Sedimentation: Later seas deposited sands and limey materials, burying parts of the hills. Subsequent river erosion re-exposed the quartzite bluffs and reopened gaps.
Ice Age and Lake Formation (~12,000–15,000 years ago): During the Wisconsin Glaciation, the glacier advanced but did not fully override the western Baraboo Hills. It deposited terminal moraines (ridges of rock, gravel, and debris) that plugged both the north and south ends of the pre-existing gorge in an abandoned river valley. This created a natural dam, trapping water and forming the lake. Without the glacier, the gorge might still be a river channel.

The lake is endorheic (closed basin) with no natural surface outlet — water enters via springs, rainfall, snowmelt, and small tributaries, and leaves primarily through evaporation. This makes levels highly sensitive to climate. The bottom sand is largely glacial in origin.
Talus slopes (piles of broken rock at the base of bluffs) formed from freeze-thaw cycles. Iconic formations include Balanced Rock, Devil’s Doorway, and various cliffs popular for rock climbing due to the durable quartzite.

Topography and Surrounding Features
Bluffs: Steep quartzite cliffs line the east and west sides, rising up to 500 feet. The East Bluff and West Bluff offer panoramic views. The North and South Bluffs complete the enclosure.
Moraines: The North Glacial Moraine ( ~80 feet thick) forms the northern shore; the Southeast Moraine (~130 feet thick) lies between bluffs.
Uplands and Valleys: Surrounding hills feature mixed conifer-deciduous forests, loess-covered soils, talus fields, and gorges like Parfrey’s Glen (a state natural area nearby with Cambrian sandstone). The broader Baraboo Range includes hardwood forests.
Trails and Access: Over 29 miles of hiking trails range from lakeshore paths to steep bluff climbs. Popular ones include the West Bluff Trail, East Bluff Trail, and Ice Age Trail segments.
The terrain supports diverse microhabitats, from rocky cliffs to forested slopes and wetlands.

Hydrology and Climate
As a closed basin, Devil’s Lake has no outflow, so levels fluctuate with precipitation and evaporation. It is spring-fed and generally clear to moderately clear. Water levels are monitored by USGS; they can rise significantly in wet periods, occasionally affecting shores and low-lying areas.
The region has a humid continental climate with cold winters, warm summers, and moderate precipitation. The lake moderates local temperatures somewhat, and the bluffs create microclimates influencing vegetation and wildlife.

Notable Geographical Elements
Rock Formations: Balanced Rock, Devil’s Doorway, and extensive talus slopes.
Biodiversity Context: The setting supports rich flora/fauna, including rare species, due to varied topography and geology.
Human Context: Effigy mounds and long Native American history (e.g., names meaning “spirit lake”). The park is heavily visited for its scenery, climbing, and trails.

 

History

Deep Geological History (Prehistoric Foundations)
The Baraboo Range’s quartzite bluffs, which frame the lake, are among the oldest exposed rock formations in North America, dating back about 1.6–1.7 billion years. Ancient rivers deposited sand into shallow seas; over time, this became sandstone and then metamorphic quartzite under heat and pressure. Tectonic forces buckled the rock into the North and South Ranges, creating a depression (the Baraboo Valley). Subsequent seas deposited more sediments, which were later eroded, exposing the resistant quartzite again.
Before the last Ice Age, the area featured a gorge carved by an ancestral river (possibly the Wisconsin or Baraboo River) flowing through a gap in the South Range. Around 15,000–20,000 years ago, during the Wisconsin Glaciation, a glacial lobe advanced, depositing terminal moraines that dammed both ends of the gorge. As the glacier retreated, meltwater and later springs/rain filled the enclosed valley, forming the lake (no surface inlet/outlet, though underground drainage may connect to the Baraboo River). The lake is about 374 acres, with depths up to 47 feet (average ~30 feet). Talus slopes, boulders, and dramatic cliffs result from freeze-thaw cycles and glacial activity.
This geology makes the site scientifically significant and a popular destination for rock climbing on the hard quartzite.

Indigenous History and Cultural Significance
Humans have used the area for at least 12,000–16,000 years (post-glacial), with Ho-Chunk (Ho-Chunk Nation, also historically Winnebago) oral traditions suggesting much deeper connections—potentially spanning multiple ice ages. The lake and surrounding lands were (and remain) sacred to the Ho-Chunk and other tribes, including Sauk, Fox (Meskwaki), and Kickapoo peoples who passed through.

Ho-Chunk name: Tee Wakącąk (or variations like Te Wakącągara, Ta-wah-cun-cunk-dah, Tewakakak), translating to “Sacred Lake,” “Holy Lake,” or “Spirit Lake”—a place where spirits live, worthy of reverence (not “devilish”). The adjacent southern land is Maa Wákąčąk (“Sacred Earth”). It features in oral histories, ceremonies, and stories (e.g., involving spiritual beings or fasting visions).
Evidence includes effigy, linear, and conical mounds built ~1,000+ years ago by mound-builder cultures (ancestors or related to Ho-Chunk), some on north and south shores. These are culturally significant burial or ceremonial sites. Historic-era Native peoples visited but did not maintain long-term settlements in the immediate valley.

European settlers often misinterpreted or reframed Indigenous spiritual sites as “Devil’s” places due to Christian cultural lenses associating non-church spirits with the demonic—a pattern seen at other U.S. sites (e.g., Devils Tower). Alternative early English names included “Lake of the Hills,” “Wild Beauty Lake,” or “Spirit Lake,” but “Devil’s Lake” prevailed by the mid-19th century.
There have been modern discussions about renaming it back to Spirit/Sacred Lake to honor the original significance.

19th-Century Exploration, Settlement, and Tourism Boom
Early European contact: John De La Ronde (1832) is the first known non-Native visitor. Naturalist Increase Lapham visited in 1849, describing challenging boulder-strewn shores.
Settlement and early development followed in the 1850s–1860s, with a bathhouse and properties like Kirkland (Noble C. Kirk, 1854) on the south shore, featuring cottages, orchards, and picnic areas.
Railroad era (1873 onward): The Chicago & North Western Railroad line along the east shore made the lake accessible from Chicago, Milwaukee, and beyond. Hotels proliferated (e.g., Minniwauken House/Cliff House and Annex on north shore, Lake View, Messenger on south). Visitors arrived by steam train for day trips or extended stays, enjoying steamers like the Capitola and Minniwauken, dances, band picnics, croquet, hayrides, regattas, and even a zoo. Ulysses S. Grant visited; elephants from circuses (linked to the Ringling Brothers, who had local ties) reportedly bathed there.
Resource extraction: Logging cleared forests (altering composition from tall oaks to smaller maples); quartzite quarries operated near the lake (blasting echoed in the valley), shipping stone by rail. A vineyard/winery also existed on the south shore.
Tourism brought economic growth but also environmental strain and overcrowding concerns.

Establishment of the State Park (Early 20th Century)
By the early 1900s, conservation sentiment grew nationally and locally. In 1906, Baraboo residents formed a committee and published “An Appeal for the Preservation of the Devil’s Lake Region,” advocating protection of scenery, geology, archaeology, and ecology while removing hotels, timber operations, and quarries. Landscape architect John Nolen highlighted the area’s potential.

1911: Devil’s Lake became Wisconsin’s third state park (after Interstate and Peninsula). The state acquired ~1,100 acres, including former hotel properties; many cottage owners sold or leased back. Early efforts focused on halting quarrying and building infrastructure.
CCC era (1930s–1940s): The Civilian Conservation Corps camp (200 young men, 1934–1941) built iconic stone structures (e.g., park headquarters, shelters, Chateau pavilion), trails with quartzite steps, roads, and more. They also fought fires, removed invasives, and improved access. Many features remain in use today.

20th Century to Present: Recreation, Stewardship, and Challenges
Camping evolved from informal setups in the 1920s–30s to developed sites like Northern Lights and Ice Age campgrounds. Golf was available for decades before conversion to camping. Attendance grew from ~100,000 (1919) to over a million annually.
The Devil’s Lake Concession Company (founded 1949, nonprofit) supports operations, food, rentals, and park funding.
Naturalists like Ken Lange (first full-time in the Wisconsin system) advanced interpretation, research, and education.
Ongoing management by the Wisconsin DNR addresses water quality (swimmer’s itch, occasional algae blooms), invasive species, rock climbing ethics, rattlesnakes, and visitor impacts. Recent expansions (e.g., land acquisitions) continue conservation. Proposals for nearby development have sparked opposition to protect the area.

 

Flora and fauna

The park spans over 9,000 acres and supports exceptional diversity due to varied habitats: upland deciduous and mixed conifer-hardwood forests (one of the largest contiguous hardwood forests in the Midwest), dry prairies, bedrock glades, oak woodlands/savannas, talus slopes, wetlands, and the lake itself. It lies mostly in the Western Coulee and Ridges ecological landscape, with a bit in the Central Sandhills.

Flora (Plants)
The park hosts around 880 plant species, reflecting its diverse microhabitats.
Forests and Woodlands: Dominant overstory includes red oak, with understory of red maple. Mixed deciduous forests feature oak, maple, basswood, and some conifers. Southern dry-mesic forests and oak woodlands are prominent, with efforts to restore them by removing invasives like buckthorn, garlic mustard, and oriental bittersweet.
Prairies, Glades, and Open Areas: Dry prairies and bedrock glades support species like prairie coreopsis, prairie alumroot, field pussy-toes, large-flowered yellow false foxglove, shooting star, columbine, wild bergamot, New England aster, Jacob's ladder, and others. Eastern prickly-pear cactus occurs in some nearby reclaimed prairie areas.
Wetlands and Aquatic Plants: The lake and associated wetlands feature native aquatics such as common waterweed (Elodea canadensis), large-leaf pondweed (Potamogeton amplifolius), fern pondweed (Potamogeton robbinsii), reeds, cattails, and water lilies. These provide fish and waterfowl habitat.
Special Areas: Parfrey's Glen State Natural Area (Wisconsin's oldest) and other SNAs (South Bluff/Devil's Nose, East Bluff, Devil's Lake Oak Forest) harbor unique and rare plants, ferns (over 20 species noted in nearby areas), and spring ephemerals like hepatica, trillium, and orchids in shaded spots.
Notable/Problematic Plants: Wild parsnip, poison ivy, nettles, poison oak, and sumac are common along trails—hikers should stay on paths. Invasives are actively managed to protect native communities.

The park's flora supports rich pollinator habitats, including for the federally endangered rusty-patched bumble bee.

Fauna (Animals)
Mammals
Up to 38–40 species reported. Common or notable ones include:

White-tailed deer (frequently seen).
Smaller mammals: raccoon, skunk, opossum, rabbit, squirrels, voles, mice, shrews, moles, woodchuck, muskrat, beaver, porcupine.
Predators and others: coyote (listen for howls), gray and red foxes, weasels, mink, otter, badger, bobcat.
Larger/rarer: black bear (occasional), mountain lion (very rare), gray wolf (rare).

Four species of bats are present. Quiet trails like Uplands, Sauk Point, or Roznos Meadow offer better mammal viewing opportunities, especially at dawn/dusk in spring or fall.

Birds
Exceptional birding: 228 species recorded, with ~105–115 nesting (nearly half of Wisconsin's total) and many migrants. Highlights include:
Waterbirds and raptors: Great Blue Heron (notable rookery on south shore), bald eagles, osprey, turkey vultures (common, especially soaring or roosting), peregrine falcons, various ducks, and warblers (multiple species).
Forest birds: Scarlet tanager, pileated woodpecker, wood duck, hooded warbler, Acadian flycatcher, owls (screech, great horned, barred, saw-whet).
Others: Flycatchers and many songbirds/migrants. Hotspots include the lake, Messenger Creek willows, Steinke Basin wetlands, and quieter wooded areas.
Spring and fall migrations are prime times.

Reptiles and Amphibians
Diverse herpetofauna:
Snakes: 10 species, including the timber rattlesnake (venomous but reclusive; slim chance of encounter—stay on trails). Also northern watersnake.
Turtles: 4 species (e.g., painted, snapping; some nesting activity).
Frogs/Toads/Salamanders: 10 frog species (spring choruses notable), 1 toad, 5 salamanders.

Fish
29 species in the lake, mostly native. Includes largemouth and smallmouth bass, walleye, northern pike, panfish (bluegill, perch common), and stocked trout (brown). Carp and white bass are non-native. Fishing is popular (license required).
Insects and Others

58 species of butterflies, including the rare white admiral.
Other invertebrates support the food web, including pollinators like bumble bees.

 

Local legends

Native American Origins and the Name
The lake formed at the end of the last Ice Age (around 10,000–12,000 years ago) as a terminal moraine filled with meltwater, now fed by springs and rainwater. It has no natural inlet or outlet, which adds to its mysterious aura.
Indigenous peoples, particularly the Ho-Chunk (Winnebago) Nation, have long regarded it as sacred. They called it variations of Ta-wa-cun-chuk-dah ("Sacred Lake," "Spirit Lake," or "Holy Lake"). Some Sioux-related names translate closer to "Mystery Lake" or "Bad Spirit Lake." European settlers translated or misinterpreted these as Devil’s Lake, likely due to associations with evil spirits, water monsters, or the dramatic, "cursed" landscape.
The area shows evidence of ancient human occupation, with stories of spirits and monsters dating back millennia.

Thunderbird vs. Water Spirits Legend (Core Creation Myth)
One of the most prominent legends explains the lake’s formation and "Devilish" nature through an epic battle between Thunderbirds (powerful, benevolent giant birds associated with thunder, lightning, and the upper world) and malevolent water spirits or monsters (underworld creatures like horned serpents/Unktehila).
According to Ho-Chunk and related traditions passed to early settlers: Water spirits inhabited a body of water here. Thunderbirds launched a massive assault, hurling thunderbolts and stones from the skies. The water spirits retaliated with boulders, waterspouts, and tempests that ensnared birds and dragged them underwater. The battle raged for days, shattering cliffs, uprooting trees, and scarring the land—creating the boulder-strewn shores and bluffs seen today.
The Thunderbirds ultimately prevailed, driving the evil spirits away (or trapping some in the depths). This victory is why the lake is sometimes called "protected by Thunderbirds." Thunderbirds were said to migrate seasonally to battle these dangers, aligning with bird migration patterns.
This myth ties into broader Native American lore of Thunderbirds battling water monsters, with Devil’s Lake as a specific "power zone" or site of ongoing spiritual conflict.

Lake Monster / Serpent Legends
Tales of a creature in the lake persist, often linked to the water spirits. Descriptions include a serpentine, fish-like, or amphibious beast resembling the Loch Ness Monster—large humps breaking the surface, massive unidentified forms, or an octopus/kraken-like entity.

During droughts (e.g., one recounted by a local chief to an early missionary), the lake allegedly split or shallowed, revealing a thrashing creature that terrified onlookers before returning to deeper water.
Sightings from bluffs or kayaks continue; some photos (including one from a 2010 kayaker that went viral as "proof") show ambiguous shapes, often debated as logs or wakes.
Ties to Unktehila (horned serpent) pushed into the lake by Thunderbirds.

Skeptics note the lake’s biology makes a breeding population unlikely, but the legends endure.

Ghostly and Apparitional Legends
Ghost stories at the lake itself are sparser than cryptid tales, but they exist:

Native American Canoe Ghost: Apparitions of a Native American paddling a ghostly canoe on the lake at night.
Chief’s Daughter / Princess Ke-she-ah-ben-o-qua Legend: A romantic tragedy where a chief’s beautiful daughter falls in love with a French trader or another figure. Variations involve her drowning (or sacrificing herself) in the lake after tragedy, with her body never recovered. Shadows of lovers or her spirit are said to appear on moonlit waters. Some accounts link it to a specific deep spot ("Devils Hole" or similar), renaming the lake "Lake of the (Evil) Spirit." A memorial plaque reportedly exists near the north end.
EVPs (electronic voice phenomena) captured by paranormal investigators at certain spots.

Related Baraboo-area hauntings (near the park) amplify the spooky vibe:
Phantom hitchhiker on Highway 12 (old army jacket or camo, vanishes if picked up).
"Ghost elephants" from Ringling Bros. Circus history—rumors of spectral pachyderms stomping, rattling houses, and even knocking down a barn in the 1930s (reported in Fate magazine and Chicago Tribune).
Haunted sites like the Old Baraboo Inn (former saloon/brothel), Al Ringling Theater, Circus World Museum, etc.

Other Cryptids and Spooky Elements
Bigfoot/Sasquatch: Occasional sightings and rumors in the park and surrounding woods, with reports of large bipedal figures.
Giant birds/Thunderbirds: Modern sightings of oversized birds overhead.
Alligator: A 1901 report of someone swearing they saw one (likely misidentification).
Real hazards like rattlesnakes on trails and seasonal midge fly swarms add to the "cursed" feel.
