Aeromagnetic Map of the Death Valley Ground-Water Model Area, Nevada and California

An aeromagnetic map of the Death Valley groundwater model area was prepared from published aeromagnetic surveys as part of an interagency effort by the U.S. Geological Survey and the U.S. Department of Energy to help characterize the geology and hydrology

Isostatic Gravity Map of the Death Valley Ground-Water Model Area, Nevada and California

An isostatic gravity map of the Death Valley groundwater model area was prepared from over 40,0000 gravity stations as part of an interagency effort by the U.S. Geological Survey and the U.S. Department of Energy to help characterize the geology and hydro

Map Showing Depth to Pre-Cenozoic Basement in the Death Valley Ground-Water Model Area, Nevada and California

A depth to basement map of the Death Valley groundwater model area was prepared using over 40,0000 gravity stations as part of an interagency effort by the U.S. Geological Survey and the U.S. Department of Energy to help characterize the geology and hydro

Digital Geologic Map of the Nevada Test Site and Vicinity, Nye, Lincoln, and Clark Counties, Nevada, and Inyo County, California

This digital geologic map of the Nevada Test Site (NTS) and vicinity, as well as its accompanying digital geophysical maps, are compiled at 1:100,000 scale. The map compilation presents new polygon (geologic map unit contacts), line (fault, fold axis, me
