About this map

The El Mirage Valley landscape along the Los Angeles and San Bernardino border defines this high desert study. Initially surveyed in 1954 and updated with 1989 aerial photography, the map reveals a remote terrain marked by prominent heights like Adobe Mtn, Nash Hill, and Gray Mtn. Human activity is sparse but evident through a network of lettered roads, including Avenue F and Avenue L, alongside more specialized developments such as several Landing Strips.

The presence of an El Mirage Off Highway Vehicle Recreation Area indicates the evolving modern use of the valley floor. Researchers interested in early exploration or mineral ventures will find various Prospects scattered across the desert, while water management is traced through the location of a Water Tank and scattered Well sites. The southern margin features Eller Slough, providing a rare hydrological detail in an otherwise arid expanse dominated by Old El Mirage Road.
