1980 Map of Pidgeon Spring SE

About this map

The Black Rock Desert dominates this 1980 survey, revealing a landscape of extreme drainage patterns and alkaline flats in Humboldt County. The most prominent hydrological feature is the Quinn River, which winds across the arid basin floor, its course marked by subtle elevation changes across the playa. This map provides a technical look at the desert's ephemeral water systems, including the Jackson Creek Slough in the northeastern portion of the quadrangle. Photogrammetric methods capture the precise topography of this desert sink, illustrating how water moves—or vanishes—within the terminal basin of northwestern Nevada. It is a study in isolation, where natural terrain features define the entire map area in the absence of roads or permanent human settlements.
