2014 Map of Tumble Mountain

About this map

Custer National Forest and Gallatin National Forest converge in this high-altitude landscape along the border of Sweet Grass and Stillwater counties. The terrain is defined by a dense concentration of subalpine lakes and dramatic peaks, centered around the high point of Tumble Mtn. The naming convention of the water bodies reflects a distinctive character, with evocative labels such as Lake Vengeance, Lake Surrender, and Lake Diaphanous clustered in the glacial basins. These lakes feed various drainage systems, including Flood Cr and Lightning Cr, which cut through the steep topography. Significant landforms like Chalice Peak and the rock formation known as Two Sisters provide clear landmarks for navigating the complex ridge lines. The absence of roads or permanent settlements emphasizes the primitive nature of this protected wilderness area in the early 21st century.
