2014 Map of Saint Marys Lake

About this map

Saint Marys Lake and the high peaks of the Flathead National Forest dominate this high-elevation landscape along the boundary of Lake and Missoula counties. The map records a complex glacial drainage system where the N Fork Mission Cr and Middle Fork Mission Cr descend through dramatic drops marked by Mission Falls and Elizabeth Falls. The geography is defined by prominent ridges and seasonal ice, including the Mountaineer Glacier, Sunrise Glacier, and Fissure Glacier, which feed a network of alpine basins such as Lucifer Lake, Picture Lake, and Lake of the Clouds. Stretching across the northeastern corner, The Garden Wall serves as a massive natural barrier, while peaks like Kakashe Mtn and West Saint Marys Peak provide significant landmarks for navigation within the wilderness. To the west, the water is managed at the Mission Reservoir, showing the intersection of natural runoff and localized water storage.
