1951 Map of Black Rock Gap

USGS Topo · Published 1953

About this map

The Sweetwater River winds through the southern reaches of this Wyoming landscape, defining a corridor of early irrigation and rugged geological formations. Surveyed for the development of the Missouri River Basin, the map documents the hydraulic engineering of the early 1950s, including the Mc Intosh-Beaton Ditch and an Abandoned Ditch that suggests shifting water management priorities on the range. The terrain is dominated by high-altitude features like the Agate Flats and the prominent Sweetwater Rocks. Landmarks such as Black Rock Gap and Quaking Asp Gap provide natural passages through the uplifted ground, while isolated water sources like Black Rock Spring and Diamond Springs Draw illustrate the sparse but vital hydrology of Fremont County's high plains.
