|Basin Fill Sandstone and Carbonate Aquifers, Basin and Range
(Arizona, Nevada, and California)
Net-sand-thickness maps of the Tertiary basin-and-range aquifers are not documented for the entire Mojave Basin and adjacent areas. However, local accumulations of more than several hundred feet of net sand are common in areas where the net upper-basin-fill thickness is more than 1 mi (>1.6 km) (Brown, 1976).
