2020 Map of Picket Pin Mountain

About this map

Gallatin National Forest and Custer National Forest dominate this high-altitude landscape in the Beartooth Mountains, where dramatic drainage systems converge. High peaks including Picket Pin Mtn and Iron Mtn overlook a complex network of alpine water bodies, from the secluded North Picket Pin Lake and South Picket Pin Lake to the headwaters of the E Boulder River. The terrain is defined by its deep basins and glacial features, such as the Placer Basin and the wide East Boulder Plateau. This 2020 survey documents the modern state of these protected wilderness areas, tracing the vital headwaters of Moccasin Lake, Divide Cr Lake, and the W Fork Stillwater River. The map illustrates how these high-elevation valleys and gulches like Burnt Gulch and Snowslide Gulch structure the region's wilderness hydrology.
