1967 Map of Massacre Mtn

About this map

Challis National Forest serves as the backdrop for this late 1960s topographic survey of high-elevation Idaho wilderness. The landscape is dominated by the steep ridges of the Lost River Range, where Massacre Mountain and Castle Peak rise above a series of glacial basins. The drainage patterns show a complex network of alpine water sources, including Long Lost Creek, Massacre Creek, and Wet Creek. Scattered throughout these heights are remote bodies of water like Copper Lake, Swauger Lakes, and Shadow Lakes. Transportation through this steep terrain is limited to established routes like the Pack Trail and Jeep Trail, indicating a region utilized primarily for forest management and backcountry access rather than permanent settlement. The presence of numerous unnamed springs further emphasizes the importance of water management within this protected federal territory.
