2011 Map of Saint Marys Lake

About this map

Saint Marys Lake anchors the southern portion of this high-alpine landscape in Missoula County, where glaciated peaks and high-elevation basins define the geography. The map captures a transition from the accessible recreation areas around Saint Marys Lake Campground and Mission Reservoir to the steep, snow-capped reaches of the Mission Range. Natural features like Sunrise Glacier and Mountaineer Glacier sit high above the basins, indicating a wilderness area where ice and stone remain prominent features. A network of glacial lakes, including Lucifer Lake, Icefloe Lake, and the aptly named No Fish Lake, are scattered among landmarks like The Garden Wall and East Saint Marys Peak. The drainage patterns of Mission Creek and Power Creek connect these high tarns to the lower campgrounds, illustrating the watershed's steep descent through features like Elizabeth Falls.
