1981 Map of Trinity Pass NW

USGS Topo · Published 1982

About this map

The Seven Troughs Range dominates the western edge of this Pershing County landscape, giving way to the broad alluvial plains of Sage Valley. This 1981 survey, based on 1974 aerial photography, reveals a remote desert environment defined by seasonal drainages and early mining interest. A single prospect is located near the northern peaks of the range, while several 4wd tracks provide the only established routes through the sagebrush. The terrain is marked by significant elevation shifts, from the heights near Burnt Canyon down into the expansive valley floor. Deep cut features like Poker Brown Canyon and Willow Canyon illustrate the erosional patterns of the Great Basin, where rare water events have carved paths through the dry soil. This map documents a quiet, industrial-adjacent wilderness where land use is limited to small-scale extraction, evidenced by a solitary Borrow Pit in the central basin.
