2017 Map of Picket Pin Mountain

About this map

Picket Pin Mtn stands as a central landmark in this high-elevation region of Montana, where the boundaries of the Custer National Forest and Gallatin National Forest meet. The landscape is defined by its complex drainage systems and alpine basins, including the notable Placer Basin and the expansive East Boulder Plateau. Water sources are abundant across the terrain, with the E Boulder River and its various tributaries such as Forge Cr and Canyon Cr carving through the mountain passes. The map identifies several secluded alpine lakes, including Moccasin Lake, Divide Creek Lake, and the tandem N Picket Pin Lake and S Picket Pin Lake. These features, alongside named points like Iron Mtn, suggest a history of prospecting and remote high-country activity common to the Sweet Grass County wilderness. The lack of major modern infrastructure underscores the preserved nature of these national forest lands in the early twenty-first century.
