About this map

McDonald Peak and West McDonald Peak anchor this high-altitude landscape along the border of Lake and Missoula counties. Within the Flathead National Forest, the terrain is defined by a series of steep drainages and alpine lakes, including Long Lake, the Ashley Lakes, and the ironically named Disappointment Lake. A network of high-elevation passages such as Mollman Pass, Elk Pass, and Eagle Pass provide the primary transit points across the divide.

Downslope, the hydrology becomes more complex as numerous creeks, including Mollman Cr and Post Cr, carve through the glacial geography. The only major roadway appearing in this wilderness area is McDonald Lake Rd, which provides access toward the lower-elevation basins. The map illustrates a strictly natural and protected environment, characterized by the intersection of county lines and national forest management.
