2015 Map of Black Rock North

About this map

Black Rock stands as a prominent landmark in this high-desert stretch of Sweetwater County, where the hydrology is defined by seasonal drainages and catchments. The landscape is carved by the Fourth of July Wash and Greasewood Wash, which channel intermittent runoff toward the southern reaches of the quadrangle. Human infrastructure is centered on water management and transit, notably at the Greasewood Reservoir and the reliable Black Rock Springs near the banks of Black Rock Cr. Mapping by the U.S. Geological Survey also details the sparse road network, including Chilton Rd and Cr-15, which provide the primary access through these expansive township sections. The map serves as a clear record of the area's arid character, punctuated only by these critical water sources and a few primitive travel routes.
