1955 Map of Adobe Mtn

About this map

Adobe Mtn and the neighboring Nash Hill define the high ground of this desert landscape, located along the boundary of Los Angeles and San Bernardino counties. The survey, based on field checks from the mid-1950s, reveals a terrain of dry lake beds and drainage patterns, including the notable El Mirage Lake and Eller Slough. The area's early 20th-century history is hinted at by scattered Prospects and the presence of a Water Tank, suggesting the persistence of small-scale mineral exploration and the infrastructure required to support activity in the arid El Mirage Valley. A rectilinear grid of roads, such as Avenue G and El Mirage Road, underscores the systematic surveying of the Mojave Desert as it was sectioned for development and access to the Shadow Mountains area.
