About this map

The Boise National Forest dominates the northeastern corner of this Elmore County landscape, where the South Fork Boise River cuts a deep path through the high desert terrain. Central to the map is the Long Tom Reservoir, a water source fed by W Fork Long Tom Cr and Willowdale Cr. This area is defined by its transition from the peaks of the Danskin Mountains and Granite Mtn to broad, high-elevation plateaus like Sproule Flat and Sage Hen Flat.

Historically significant routes cross this region, including the NE Immigrant Rd in the southwest and the Long Tom (Dixie Cutoff) further north. These tracks, along with the Cow Creek Jeep Trail, trace the movement of early travelers and livestock through this part of Idaho. Local landmarks such as Tollgate Hill and numerous named water sources like McGuire Spring and Timmons Field Spring provide specific points of interest for those tracing the development of land use and transit in the high country.
