About this map

Danskin Mountains terrain and high-desert water sources define this landscape within the Boise National Forest as it was documented in 1990. The map centers on the Long Tom Reservoir, a vital catchment fed by Long Tom Creek. This area of Elmore County is characterized by a sparse settlement pattern, with the Long Tom Ranch serving as a primary landmark alongside primitive 4WD tracks and cattle-grazing infrastructure.

The South Fork Boise River cuts through the northern section, flanked by notable high points such as Indian Point and Tollgate Hill. Numerous family-named and geographic water sources, including McGuire Spring, Berneathy Spring, and Pole Spring, reveal the importance of reliable water in this upland environment. Broad expanses like Sproule Flat and Sage Hen Flat provide a clear view of the benchland topography above the river drainage.
