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, Qf4-

Seismic-reflection profiles of the New Madrid seismic zone-data along the Mississippi River near Caruthersville, Missouri

The tectonic setting and the earthquake hazards of the New Madrid seismic zone in the northern Mississippi embayment have been the subject of intensive study the past several years as part of the Earthquake Hazard Reduction Program of the USGS (U.S. Geological Survey). These efforts have improved our knowledge of the geologic history, general tectonic setting, and patterns of modern seismicity (se
