Grass Valley and the western slopes of the Sonoma Range dominate this 1990 provisional study, marking the high-desert boundary between Pershing and Humboldt Counties. The landscape is defined by the transition from the broad, arid valley floor to the steep drainages of Grand Trunk Canyon and Washoke Canyon. Water management is central to the area's utility, evidenced by the presence of Clear Creek Ranch and isolated water sources like Turner Well and the Lower Grand Trunk Reservoir. Evidence of early or exploratory industry appears in the form of several Prospects and a Shaft located along the mountain flanks. These features, along with scattered Corrals and numerous Gravel Pits, suggest an economy balanced between ranching and mineral exploration in the Nevada interior.
