About this map

Lewis and Clark National Forest encompasses this high-altitude landscape of the northern Rocky Mountains as it was documented in the late 1950s. The geography is defined by prominent limestone features such as Black Reef and Windfall Reef, while the central hydrology is dominated by the Gibson Reservoir on the North Sun River. Human activity in this wilderness area is marked by the presence of the Klick Lower Ranch near the reservoir's spillway and several isolated structures like the Sheep Sheds situated along the high basins.

A complex network of drainages including Lange Creek, Stovepipe Creek, and Beaver Creek feeds into the larger river system, punctuated by landmarks like Lange Falls and the deep Elbow Gorge. The terrain rises sharply to summits including Allan Mountain and Renshaw Mountain, which separate major depressions like Patricks Basin and Beaver Basin. Access during this era was largely restricted to primitive routes, including an extensive Pack Trail system traversing the mountain passes.
