Resource Abstract:
- description: This geologic map database for the El Mirage Lake area describes geologic materials for the dry lake, parts of
the adjacent Shadow Mountains and Adobe Mountain, and much of the piedmont extending south from the lake upward toward the
San Gabriel Mountains. This area lies within the western Mojave Desert of San Bernardino and Los Angeles Counties, southern
California. The area is traversed by a few paved highways that service the community of El Mirage, and by numerous dirt roads
that lead to outlying properties. An off-highway vehicle area established by the Bureau of Land Management encompasses the
dry lake and much of the land north and east of the lake. The physiography of the area consists of the dry lake, flanking
mud and sand flats and alluvial piedmonts, and a few sharp craggy mountains. This digital geologic map database, intended
for use at 1:24,000- scale, describes and portrays the rock units and surficial deposits of the El Mirage Lake area. It was
prepared as part of a water-resource assessments of the area, describing and interpreting surface geology that provides information
to help understand distribution and extent of deeper groundwater-bearing units. The area mapped covers the Shadow Mountains
SE and parts of the Shadow Mountains, Adobe Mountain, and El Mirage 7.5-minute quadrangles. The map database includes detailed
geology of surface and bedrock deposits, which represent a significant update from previous bedrock geologic maps by Dibblee
(1960) and Troxel and Gunderson (1970), and the surficial geologic map of Ponti and Burke (1980); it incorporates a fringe
of the detailed bedrock mapping in the Shadow Mountains by Martin (1992).; abstract: This geologic map database for the El
