This property best tells the story of the draining of the ancient Glacial Lake Wisconsin at the end of the most recent glaciation of Wisconsin 12,000 – 15,000 years ago.  The Dells of the Wisconsin River State Natural Area is a hidden natural treasure that hugs the shoreline of the Wisconsin River and bounds the city of Wisconsin Dells both to the north and to the south.  The state-owned property spans 1,300 acres and includes five miles of Wisconsin River shoreline—the iconic and breathtaking “dells” that have contributed to the area’s popularity.  (Yes, the dells of the Wisconsin River existed before waterparks!)    The site protects several rare plant communities, including a nice example of northern dry forest dominated by red, black and white oak, white pine and hemlock.  The steep cliffs and deep glens harbor a number of rare species found nowhere else in the state.  For this reason much of the property is off-limits to visitors.  However, the property offers a delightful respite from the congested commercialism of the Dells.

It's an easy hike to the River from the main parking lot

It’s an easy hike to the River from the main parking lot

From the parking lot on the west side of River Road north of the Dells, an easy trail meanders through forested land toward the River where one can glimpse the beautiful sandstone bluffs before returning to the parking areas via a loop trail.  Stay alert—the rare red-shouldered hawk and pileated woodpecker among many other bird species make this woodland home.

Although the sandstone layer is ancient (510+ million years), the dells themselves were formed very recently (geologically speaking) when the ancient Glacial Lake Wisconsin broke through a thin dam at this site some 12,000 or so years ago and the massive quantity of backed-up water eroded– in a matter of days (!)– what we experience today as the dells.  The dam on the Wisconsin River at Wisconsin Dells has backed up the river water, covering many feet of the bluffs.  Nonetheless, the bluffs still stand in some places 100 feet above the River offering breathtaking views.
