1985 Map of Sandrock Canyon

About this map

The Black Pine Mountains dominate the eastern half of this 1985 survey, where the Sawtooth National Forest boundary protects a network of steep drainages and essential water sources. This interior landscape in Cassia County is defined by its canyon systems, including Sandrock Canyon, Eightmile Canyon, and Big Canyon. Scattered throughout these draws are numerous named springs such as Boosinger Spring, Mortenson Spring, and Fisher Spring, which historically supported livestock and wildlife in this arid Idaho environment. Small-scale human improvements are evident in the form of a Well and several Corral sites, illustrating the area's continued use for grazing and forest management in the late 20th century.
