1982 Map of Seven Troughs NW

USGS Topo · Published 1982

About this map

Bluewing Mountains and the rising slopes of the Seven Troughs Range dominate this 1982 Pershing County landscape. The topography captures the stark transition between high-desert ridges and the expansive basin floors of Kumiva Valley and Granite Springs Valley. Compiled from 1970s aerial photography, the map documents an arid environment where water is a critical but rare landmark, specifically noting a isolated Spring at the base of the mountains. The survey reflects the isolated character of this region, defined by unimproved roads and bench marks that serve as the primary markers of human surveying across the Great Basin terrain.
