Ibex Peak anchors this high-elevation corner of the Sawtooth National Forest, situated where the Idaho, Nevada, and Utah state lines converge. In the early 21st century, this remote landscape remained a domain of specialized ranching and exploration, evidenced by the Frish Ranch and Emery Ranch. The map highlights a network of mountain springs and canyons, including Joes Mountain and the distinctive Hole in the Wall terrain. Human activity is marked by isolated infrastructure like Wards Corral and the Prospect Worthington Mine, suggesting a history of small-scale mineral prospecting. Movement through the steep topography of Cassia Co is traced by persistent 4wd tracks that bridge high passes such as Beaverdam Pass and Daves Pass, connecting the drainages of Fall Creek and Beaverdam Creek.
