Devil's Lake State Park

Devil's Lake State Park is a state park located in the Baraboo Range in eastern Sauk County, just south of Baraboo, Wisconsin. Devil's Lake State Park is the largest state park in Wisconsin. It is around thirty-five miles northwest of Madison, and is on the western edge of the last ice-sheet deposited during the Wisconsin drift. This 9,217-acre state park is known for its 500-foot-high quartzite bluffs along the 360-acre Devil's Lake, which was created by a glacier depositing terminal moraines that plugged the north and south ends of the gap in the bluffs during the last ice age approximately 12,000 years ago. The sand at the bottom of Devil's Lake is thought to be deposited by glaciers.

There are many quartzite rock formations, such as Balanced Rock and Devil's Doorway, throughout the park. Effigy mounds are also located throughout the park.
