1991 Map of Sentinel Rock

USGS Topo · Published 1991

About this map

Sentinel Rock stands as a prominent landmark at the center of this terrain where the high elevations of the Double H Mountains descend into the Quinn River Valley. This remote landscape in Humboldt County is defined by the drainage patterns of Crowley Creek, Pole Creek, and Cherry Creek, which flow toward the north-south corridor of the Quinn River. Evidence of land use is sparse but specific, with a Prospect in the north and a Borrow Pit and Quarry further south, suggesting localized mineral exploration and material extraction. A long Transmission Line cuts across the valley floor, marking the encroachment of infrastructure into the Great Basin. The map identifies critical water sources in this arid environment, including a Spring, Well, and Water Tank, which were essential for both livestock and early surveying efforts.
