Barry Moring 1986 <p>Sedimentary deposits of northern Death Valley include units of alluvial, eolian, lacustrine, and spring origin. &nbsp;The alluvial deposits, which include both fan and pediment deposits, predominate. &nbsp;Fan deposits are divided into four major units; locally one of these is further divided into three subunits. &nbsp;Pediment deposits may be divided into two subunits. &nbsp;Hyphenated map symbols (for example, Qf_4-3) are used where two deposits cannot be separated at the map scale; symbols separated by a slash indicate areas where thin veneers of younger deposits overlie old deposits (for example, Qf₃/Qp₂).</p> application/pdf 10.3133/mf1770 en U.S. Geological Survey Reconnaissance surficial geologic map of northern Death Valley, California and Nevada reports
