NPS

The Ice Age National Scenic Trail exists through the dedicated efforts of partners and volunteers.

The National Park Service partners with the State of Wisconsin and the Ice Age Trail Alliance to administer the trail and cooperates with federal, state, and local agencies as well as organizations, landowners, and businesses to protect, develop, manage, and maintain the trail.

Our primary state-wide partners include the Wisconsin Department of Natural Resources (WDNR) and the Ice Age Trail Alliance (IATA).

Many local partners also contribute to the trail by developing and managing individual segments. These partners include the U.S. Forest Service; county and municipal park and forestry departments; conservation, civic, and youth organizations; and private landowners.

The NPS, WDNR, and IATA have a formal Agreement to cooperate in the completion and long term management of the trail.

Ice Age Trail Alliance

Ice Age Trail Alliance

The Ice Age Trail Alliance is a non-profit, volunteer- and member-based organization established in 1958. Their mission is to protect, promote, build and mantain the many segments of the Ice Age Trail. Today the Alliance has more than 5,000 members in 40 states with volunteers organized into 21 local chapters along the Ice Age Trail.

Wisconsin Department of Natural Resources

The Wisconsin Department of Natural Resources manages many of the permanently protected segments of the Ice Age Trail. The Department also administers the nine-unit Ice Age National Scientific Reserve which was established in 1971.

In 1987, the Wisconsin legislature designated the Trail as the first State Scenic Trail. Three years later, the legislature enacted the Stewardship Program, a fund from which monies are available to assist in acquiring lands for the Ice Age Trail.
