About this map

Sunshine Peak dominates this arid landscape within San Bernardino County, where volcanic activity and military operations intersect. Vast fields of Lava characterize the northern and southern reaches of the quadrangle, with the prominent Pisgah Crater situated in the northeast. The mid-century era shown here marks a transition into specialized desert land use, as indicated by the extensive Marine Corps Training Center and the demarcated Naval Reservation Boundary.

Resource extraction was active during this period, evidenced by a concentration of small-scale mining operations scattered across the mountains. Prospectors and mining companies established sites such as the National Lead Mine, Silver Cliffs Mine, and the Imperial Lode Mine. These workings, along with others like the Tip Top Mine and Mowry Mine, illustrate the economic drive to tap into the mineral deposits of the California desert. The reliance on scarce water sources is underscored by the solitary Spring located near the eastern lava flows.
