- This National Scenic Trail stretches 1,200 miles east to west but it crosses no state borders, the trail is located entirely within one state.
- The trail is administered by the National Park Service but the trail passes through many local parks, state parks, a national forest and through hundreds of private citizen's land.
- The trail was established by an Act of Congress in 1980, in large part as a result of the efforts of a Congressman, who in 1976 authored a book called On the Trail of the Ice Age.
However, the origins of the trail date back to the 1950s when a trail foundation was established in hopes of establishing a national park in the area.
- The trail, for the most part, follows the moraine from that last ice age. Geologic scenery includes include kettles, potholes, eskers, and glacial erratics.
- In addition to backpacking and hiking, this trail hosts a popular 50 Mile and 50K race. Founded in 1982, this is one of the country's classic ultramarathons.
