About this map

El Mirage Field occupies the high desert floor of El Mirage Valley, marking a landscape defined by aviation and early infrastructure in the mid-1950s. The northern reaches are dominated by the broad expanse of El Mirage Lake, a dry bed serving as a natural focal point for the region. To the east, the rising elevations of the Shadow Mtns break the flat horizon, while Gray Mtn anchors the western edge of the survey.

A network of unimproved and light-duty roads connects these arid stretches, including the historic path of Old Phelan Road and Tanner Road. The southern portion of the sheet shows the development of the Pearblossom Highway, a vital corridor crossing the desert. Local rural routes like Sheep Creek Rd and Beekley Rd indicate the early grid system that shaped this portion of San Bernardino County before modern expansion.
