About this map

El Mirage Valley serves as the focal point of this arid high-desert landscape on the border of Los Angeles and San Bernardino counties. The mid-century terrain is defined by isolated peaks rising from the alluvial plain, including Mt Elmo, Black Mtn, and the prominent Black Butte. A notable piece of aviation history is recorded at Gray Butte Field, marked as abandoned by the time of this survey.

Resource extraction and water management are evident through numerous scattered quarries, mine shafts, and prospects, alongside a network of reservoirs and the reliable Moody Springs. Transportation infrastructure during this era is anchored by the Southern Pacific railroad line and the Pearblossom Hy in the south, while the northern sections are crisscrossed by a grid of numbered avenues including East Avenue P and East Avenue Q.
