About this map

El Mirage Valley serves as the focal point of this mid-century survey, straddling the border between Los Angeles County and San Bernardino County. The landscape is defined by its prominent volcanic and crystalline formations, including the high peaks of Black Butte and the Three Sisters. In the northern section, Moody Springs and Eller Slough provide rare water sources in an otherwise arid expanse dotted with numerous small reservoirs.

Evidence of early aviation and industrial activity is present through the Gray Butte Field (Abandoned) and various mining operations. Scattered shafts, quarries, and prospects are located near Mt Elmo and Black Mtn, signaling the area's resource extraction history. The gridded road system, featuring East Avenue O and Palmdale Boulevard, reveals the early stages of desert subdivision and connectivity during the 1950s.
