This digital data set defines the boundaries of the deserts of the southwestern United States. Those deserts include the Great Basin, Mojave, Colorado, and Sonoran Deserts as defined by Benson and Darrow (1981). The study by Benson and Darrow (1981) was a historical reference used to support development of the transient ground-water model of Death Valley regional ground-water flow system (DVRFS) completed in 2004 by the USGS (see "Larger Work Citation", Chapter A, page 8, for details).
