The Continental Divide defines the spine of this 1988 survey, marking the high-altitude boundary between Montana and Idaho and the jurisdictional line for Beaverhead and Clark counties. The northern landscape transitions from the open Centennial Valley, where the 7L Ranch and a small Cem are located, into the densely forested slopes of the Targhee National Forest. High-country resource extraction is evidenced by a Coal Mine and a Prospect located near Coon Creek in the central portion of the sheet.
