About this map

The East Mojave National Scenic Area dominates this mid-1980s landscape, illustrating a vast region of the high desert before its transition into a formal national preserve. The map highlights the rugged geology of the Cinder Cone Lava Beds and the symmetrical Cima Dome, surrounded by the wide expanses of Ivanpah Valley and Lanfair Valley. Human activity is concentrated along the Union Pacific railroad corridor, which connects small settlements like Cima and Nipton to the broader regional economy.

Mineral extraction is a primary feature of the terrain, with numerous historical workings such as the Morning Star Mine, Standard Mine, and Vontrigger Mine scattered throughout the New York Mountains and the Piute Range. To the southwest, the drifting sands of the Devils Playground and the Sand Dunes mark the edge of the desert floor, providing a stark contrast to the volcanic features and high peaks of the Mescal Range.
