About this map

Death Valley National Park encompasses the southern half of this High Sierra terrain, where the high desert landscape meets the eastern edge of Inyo County. The namesake Joshua Flats sits in the northwest corner of the quadrangle, a high-altitude basin bordered by the elevations of Lime Hill. This area is defined by its isolation and limited infrastructure, primarily serviced by the primitive Loretta Mine Rd winding through the northern sections.

The topography transitions sharply into the Cowhorn Valley in the west, illustrating the dramatic drainage patterns typical of the region's rain-shadow environment. For the local historian or surveyor, this map documents the precise 2018 boundaries of the national park and the existing network of 4WD tracks and trails that provided the only access to these remote reaches of the California desert at the time of the survey.
