1951 Map of Black Rock Gap

About this map

The Sweetwater River winds through this high-elevation landscape in Fremont County, creating a critical riparian corridor between the southern and northern ranges of the Granite Mountains. This mid-century survey reveals a territory defined by early water management and natural landmarks, where the Mc Intosh Benton Ditch and other irrigation channels parallel the river's path. To the north, the terrain transitions into the broad expanse of the Agate Flats, broken by dramatic geological features like Black Rock Gap and Quaking Asp Gap.
