Surface altitudes of hydrogeologic units used in the hydrogeologic framework and transient ground-water flow model of the Death Valley regional ground-water flow system, Nevada and California
A digital three-dimensional (3D) hydrogeologic framework model (HFM) represents the geometry 
and extent of hydrogeologic units (HGUs) and major structures in the Death Valley regional 
ground-water flow system (DVRFS). The HFM altitude data represent the geometry of the HFM 
by defining the top of the 27 HGUs in an …
