Natural History
The bluffs along the Wisconsin River are formed of Jordan Sandstone. The park lies within the Driftless Area, a region of the American Midwest that remained ice-free through three successive ice ages. In the 19th century the Wisconsin River flowed directly past the base of the bluffs. The river has since shifted slightly, and a stream known as Mill Creek marks the northern boundary of the park.
