2017 Map of Saint Marys Lake

About this map

Saint Marys Lake and the high peaks of the Flathead National Forest dominate this landscape along the border of Missoula and Lake counties. The area is defined by sharp topographic relief, where the Mission Mountains transition into deep glacial basins. High-altitude hydrology is a focal point, with Lake of the Stars and Icefloe Lake feeding into drainage systems like the Middle Fork Mission Cr. Dramatic vertical features such as The Garden Wall and Mountaineer Peak mark the eastern divide, while Elizabeth Falls provides a significant landmark along the descent toward the Mission Reservoir. A few service routes, including St Marys Lake Rd and Mission Dam Rd, provide limited access to these high basins, illustrating the era's balance of resource management and wilderness preservation in the northern Rockies.
