Rocky Springs Segment of the Whoop-Up Trail
The Rocky Springs Segment of the Whoop-Up Trail was the location of campsites for travellers along the Whoop-Up Trail between Fort Benton, Montana, and Fort Hamilton, Alberta, in the 19th century. In 1991, it was the best-preserved segment of the Whoop-Up Trail within Montana and it included rut tracks still visible and the surrounding landscape was mostly natural.
