About this map

The Silver City Range dominates this mid-1960s landscape, illustrating the high-desert mining and ranching geography of Owyhee County. Mining activity is evident through sites like the Affehtought Mine and numerous prospect markers, particularly around peaks with mineral-driven names like Cinnabar Mtn and Quicksilver Mtn. These peaks are connected by a network of jeep trails that navigate difficult passes such as Toy Pass and Pickett Creek Saddle.

Remote ranching infrastructure is anchored by the small settlement of Triangle and the nearby Triangle Corral Flat. The drainage system is extensive, with Jordan Creek and Boulder Creek carving through the terrain. Evidence of seasonal or specialized habitation appears at Snow Cabin, while topographic landmarks like Henderson Point and China Butte provide orientation across the high basins and ridges.
