1955 Map of Adobe Mtn

About this map

El Mirage Valley serves as a stark desert landscape where the boundary between Los Angeles and San Bernardino counties cuts through a series of isolated peaks and dry lake beds. The prominent volcanic profile of Adobe Mtn and the neighboring Nash Hill dominate the central terrain, offering a clear view of the sparse settlement patterns in the High Desert during the mid-twentieth century. Transportation is defined by a rigid grid of graded paths such as East Avenue G and Shadow Mountains Road, while more localized aviation is represented by several isolated Landing Strips. Traces of small-scale mining activity appear as scattered prospects, particularly on the slopes of Gray Mtn and near the northern edge of the survey area. The presence of Eller Slough and various wells indicates the critical role of groundwater in this arid region, where the vast expanse of El Mirage Lake marks the eastern margin.
