2014 Map of Mount Calowahcan

About this map

Mt Calowahcan and the surrounding high country of the Flathead National Forest dominate this 2014 survey along the border of Lake and Missoula counties. The terrain is defined by a series of high mountain passes, including Mollman Pass, Elk Pass, and Eagle Pass, which historically served as critical transit points through the Mission Mountains. The hydrologic landscape is equally complex, featuring a dense network of glacial lakes such as McDonald Lake, Ashley Lakes, and Summit Lake. Notably, the presence of the McDonald Glacier near McDonald Peak and West McDonald Peak illustrates the high-altitude environment. The map details the drainage patterns of significant waterways like Post Creek and Mollman Creek, which flow from these alpine basins. This modern topographic record captures the wilderness character of the region, emphasizing the prominent peaks and the glacial features that shape the headwaters of the local creek systems.
