2011 Map of Tumble Mountain

About this map

Tumble Mountain and Chalice Peak dominate a landscape defined by an exceptional concentration of high-elevation water bodies and drainage basins in Sweet Grass County. This 2011 survey reveals a complex network of alpine lakes and creeks that flow from the Lake Plateau, including curiously named features such as Lake Vengeance, Lake Surrender, and Wounded Man Lake. The hydrography is characterized by several distinct creek systems, notably Lightning Creek, Flood Creek, and Saderbalm Creek, which carve through the terrain beneath landmarks like the Two Sisters. The density of these named water features, from Lake Pinchot to Lake Diaphanous, suggests a wilderness area where specific topographical landmarks served as vital reference points for early surveyors and travelers navigating the high country.
