About this map

The Salmon National Forest defines this high-elevation Idaho landscape, where the Old Indian Treaty Boundary carves a significant historical line through the terrain. The topography is anchored by Poison Peak and Watson Peak, overlooking a complex system of drainages and seasonal water sources. The map provides a detailed view of remote water management and natural catchments, such as the Bull Summit Waterhole, Tule Lake, and numerous named springs like Porcupine Spring and Andrews Spring.

Navigation through these mountains relied on a network of routes labeled Jeep Trail, connecting distinct basins and canyons. Local geographic features like Copper Basin, North Basin, and First Basin are clearly delineated alongside drainage systems including Haynes Creek, McDevitt Creek, and Twelvemile Creek. The prevalence of water-related nomenclature in this high-country setting reflects the critical importance of reliable springs and creek-fed meadows like Twelvemile Meadow for the ranching and forestry operations of the early 1960s.
