Reconnaissance surficial geologic map of northern Death Valley, California and Nevada Reconnaissance surficial geologic map of northern Death Valley, California and Nevada
Sedimentary deposits of northern Death Valley include units of alluvial, eolian, lacustrine, and spring origin. The alluvial deposits, which include both fan and pediment deposits, predominate. Fan deposits are divided into four major units; locally one of these is further divided into three subunits. Pediment deposits may be divided into two subunits. Hyphenated map symbols (for example...
