2010 Map of Fence Canyon

About this map

Graham Ranch serves as a lone human landmark in this arid stretch of Sierra County, marking a site of habitation and cattle ranching in the high desert. The landscape is defined by the drainage patterns of Fence Canyon and Middle Canyon, which cut through the limestone and gypsum deposits of the Gyp Hills. Water management is the primary logistical concern of this era, as evidenced by a network of named catchment basins including Bull Pasture Tank, Army Tank, and Fuller Tank. These features are connected by a series of graded routes such as County Rd-A029 and County Rd-A030, reflecting the continued importance of ranching infrastructure and land access in the early 21st century.
