2020 Map of Lem Peak

About this map

Lem Peak stands as the primary landmark within this high-elevation section of the Lemhi Range, dominating a landscape shaped by glacial basins and alpine drainage systems. As part of the Salmon National Forest, the terrain is defined by steep ridges like Long Ridge and deep catchments such as First Basin and Hayden Basin. The map reveals a complex network of headwaters, with Basin Creek and McNutt Cr carving through the northern slopes, while the southern reaches feed into Kadletz Creek and Hayden Creek. Water distribution is centered on several high-mountain clusters, including Basin Lake, Buck Lakes, and the Bear Valley Lakes. Access through this wilderness is traced by specialized routes such as Basin Creek Rd, Trail Creek Rd, and the Hayden Creek Loop, illustrating the infrastructure required for forest management and backcountry navigation.
