1955 Map of Shadow Mountains SE

About this map

El Mirage Field and the expansive dry bed of El Mirage Lake define this high desert landscape in San Bernardino County. In the mid-1950s, the region was characterized by the broad El Mirage Valley, flanked by the Shadow Mtns to the northeast and Gray Mtn to the west. This survey illustrates a period of emerging transit and infrastructure, with Pearblossom Highway cutting across the southern portion of the sheet. A network of rural routes, including Tanner Road, Old Phelan Road, and Sheep Creek Rd, suggests an era of early homesteading and localized development before the heavy suburban expansion of the later 20th century. Notable water resources are sparse, marked only by scattered features like a Well and a small Reservoir, reflecting the arid environmental challenges of this desert interior.
