1972 Map of Prohibition Flat

About this map

Prohibition Flat serves as the focal point of this 1970s landscape, positioned along the border between Nevada and Utah. This arid, high-desert terrain is defined by its water sources and drainage patterns, including the prominent Rose Valley Reservoir and numerous ephemeral channels such as Midnight Wash and Gold Springs Wash. The eastern portion of the sheet is dominated by the Paradise Mts, where seasonal springs like Mud Spring and Trough Spring provided critical resources for early activity in the region. Evidence of historical exploration and small-scale resource extraction is visible through several marked Prospect sites. The map clearly delineates the Nevada-Utah state line and the junction of Lincoln and Iron counties, illustrating how these political boundaries intersect with the natural geography of the Great Basin.
