About this map

The Silver City Range dominates this 1990 survey of the Owyhee high country, where high-altitude peaks and drainage systems define the landscape. Notable elevations like Red Mountain and Henderson Point overlook a complex network of canyons and gulches, including Castle Creek and Bates Creek. The map documents a rugged environment where water sources were critical for both survival and industry, marked by the location of Alibi Spring, Henderson Springs, and Charity Spring.

Human activity is primarily represented by transportation routes and evidence of mining. The Bachman Grade and various 4WD tracks trace the contours of the terrain, providing access to remote landmarks such as Toy Pass and Hyde Saddle. The presence of Tailings near the Silver City Range points to the area's prospecting history, while named flats like Toy Flat suggest small pockets of level ground in an otherwise steep, creek-cut geography.
