2017 Map of Black Rock North

About this map

Greasewood Reservoir sits at the heart of this high-desert landscape in Sweetwater County, serving as a vital water collection point in an arid region defined by seasonal drainages. The topography is shaped by the intermittent flows of Fourth of July Wash and Greasewood Wash, which carve subtle paths across the sagebrush-covered plains. Sparse infrastructure is represented by primitive routes like Chilton Rd and Co Rd 83, highlighting the isolation of the Red Desert area. Near the southern boundary, Black Rock Springs and the headwaters of Black Rock Cr provide rare reliable water sources in this stretch of the Wyoming backcountry, where the public land survey system remains the primary method for navigating the expansive open range.
