About this map

The high desert landscape of the Sawtooth National Forest is defined here by a dense network of mountain springs and remote cattle ranching infrastructure. At the center of this 1970s survey, Ibex Peak rises over a terrain dominated by named water sources like Hole in the Wall Spring and Chalk Spring, which sustained the area's livestock operations. Traces of human activity are concentrated around features like Wards Corral and Owens Corral, while the south reveals a transition into the Minidoka State Bird Sanctuary.

Resource extraction and seasonal habitation are documented through the presence of the Worthington Mine and several family-named outfits, including Emery Ranch and Beaverdam Ranch. This map illustrates how the drainage patterns of Carlson Creek and Beaverdam Creek dictated the placement of early settlements and trails in this tri-state corner where Idaho, Utah, and Nevada converge near the boundary of Cassia and Elko counties.
