The Clam Falls Trail, an abandoned road that served as an important thoroughfare during the logging era, also traverses the park roughly parallel to the Ice Age Trail.

Lake Shetek State Park: Lake Shetek State Park is a state park of Minnesota, United States, on Lake Shetek, which is the largest lake in southwestern Minnesota and the headwaters of the Des Moines River.  It is most popular for water recreation and camping.

It began on August 17, 1862, along the Minnesota River in southwest Minnesota.  The war saw extensive attacks on hundreds of settlers and immigrants, and caused many to flee.  Intense desire for immediate revenge ended with the mass execution of 38 Dakota men on December 26, 1862, in Mankato, Minnesota.

Jackson Lake State Park (Ohio): Jackson Lake State Park is a 349 acre Ohio state park in Jackson County, Ohio, in the United States.  The park was established as a state park in 1979.  It had previously been a "state reserve", similar to a park but with less development.

Recreational activities available at the park include camping, boating, fishing, swimming and picnicking.

Flandrau State Park: Flandrau State Park is a state park of Minnesota, United States, on the Cottonwood River adjacent to the city of New Ulm.  Initially called Cottonwood River State Park, it was renamed in 1945 to honor Charles Eugene Flandrau, a leading citizen of early Minnesota who commanded defenses during the Battles of New Ulm in the Dakota War of 1862.

Devil's Lake State Park (Wisconsin): 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 biggest 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 9217 acre state park is known for its 500 ft 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.  Devil's Lake is situated in the Baraboo Hills.  The Baraboo Hills are thought to be much older than Devil's Lake itself; they are approximately 1.6 billion years old and were once part of the Baraboo Range which is thought to have been taller than the Rocky Mountains.

Battle of Wood Lake: The Battle of Wood Lake was a battle in the Dakota War of 1862 in September.  By that time in the Dakota War of 1862, the Sioux offensive had slowed considerably, and the Minnesota forces were beginning to implement a plan formulated by Governor Alexander Ramsey.  Ramsey's plan, implemented by Colonel Henry Hastings Sibley and frontier commander Charles Eugene Flandrau, had the goals of freeing settlers held captive by the Indians and to "exterminate" or drive the Dakota "forever beyond the borders of the state".
