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.

Famous quotes related to natural history:
“To a person uninstructed in natural history, his country or sea-side stroll is a walk through a gallery filled with wonderful works of art, nine-tenths of which have their faces turned to the wall. Teach him something of natural history, and you place in his hands a catalogue of those which are worth turning round.”
—Thomas Henry Huxley (1825–95)
