About this map

Salmon National Forest dominates this 1991 provisional survey of the Idaho backcountry, revealing a landscape shaped by high-elevation drainage systems and scattered resource extraction. The map detail centers on Pine Creek Ridge, where steep gulches like Arrastra Gulch and Sawmill Gulch suggest a history of local industry or timbering. The presence of a Prospect near East Fork Boulder Creek and Boulder Meadow indicates the continued search for minerals in these remote reaches of Lemhi County.

Water plays a central role in the topography, with numerous tributaries such as Beaver Creek, Moose Creek, and Arnett Creek carving through the terrain from peaks like Stormy Peak and Haystack Mountain. This era of USGS mapping provides a clear look at the primitive road network and mountain trails that provided access to the high country before modern developments altered the wilderness character of the region.
