About this map

The Hawthorne Army Ammunition Plant dominates the transition between high desert peaks and the expansive Walker Lake Valley in this late twentieth-century survey. This region of Mineral County is defined by the steep elevation changes from the Wassuk Range in the west to the Garfield Hills in the east. Of particular interest to local historians is the location of Oro City (Site), a former settlement now marked only as a site, and numerous mining signatures scattered across the terrain. Remnants of the area's prospecting history are visible through several prospects and a documented Mine Shaft located south of the ammunition plant. The map traces the winding paths of Pamlico Canyon and Bromide Canyon, highlighting the complex drainage patterns that lead toward the valley floor, while Cottonwood Creek provides a rare watercourse through the arid landscape.
