About this map

The Wah Wah Mountains dominate this high-desert portion of Beaver County, marking a sharp transition into the Wah Wah Valley to the east. This modern survey shows a landscape defined by intermittent water management, where the arid terrain is punctuated by man-made catchments like Brimstone Reservoir, Miners Hill Reservoir, and Grover Wash Reservoir. These features, along with the natural Willow Spring, represent the critical infrastructure required for ranching and survival in this remote Great Basin environment.

Drainage patterns across the quadrangle are primarily seasonal, with Quartz Cr and Willow Cr descending from the higher elevations of the range. To the east, the broad flats of the valley floor are marked by the Wah Wah Wash and Grover Wash, illustrating the massive alluvial fans that spread from the mountain base. The map reveals the intricate network of primitive roads and 4WD tracks that provide the only access through this desolate and sparsely populated area.
