1989 Map of May Mountain

USGS Topo · Published 1989

About this map

May Mountain and Long Mountain dominate this central Idaho landscape, serving as the boundary between two major federal wilderness management zones. The map illustrates the convergence of the Salmon National Forest and Challis National Forest, where a complex network of high-elevation drainages shapes the terrain. Elaborate water systems including Morgan Creek and its North Fork Morgan Creek carve through the western slopes, while the headwaters of Hayden Creek and its West Fork Hayden Creek define the eastern valleys. This late-twentieth-century survey captures the area as it appeared before many modern administrative adjustments, recording the precise locations of remote features like Spring Gulch and Tater Creek. The cartography emphasizes the intricate drainage patterns that have historically dictated access and resource management in this portion of Lemhi County.
