Hydrostructural Maps of the Death Valley Regional Flow System, Nevada and California--Map A: Structural Framework, Neogene Basins, and Potentiometric Surface; Map B: Structural Framework, Earthquake Epicenters, and Potential Zones of Enhanced Hydraulic Conductivity

The locations of principal faults and structural zones that may influence ground-water flow were compiled in support of a three-dimensional ground-water model for the Death Valley regional flow system (DVRFS), which covers 80,000 square km in southwestern

Aeromagnetic expression of buried basaltic volcanoes near Yucca Mountain, Nevada

Mathematical modeling and analysis of aeromagnetic anomaly data (gridded data provide in another report).

Preliminary gravity inversion model of Frenchman Flat basin, Nevada Test Site, Nevada

The depth of the basin beneath Frenchman Flat is estimated using a gravity inversion method. This dataset is distributed as an XYZ ASCII format data file generated from the 2002 gravity inversion model of the bedrock beneath Frenchman Flat basin. Data fo

Hazard maps of the U.S.

The coverages were created using the gridded data available from this ftp site. Most of the gridded data for the United States is at a spacing of 0.1 degrees latitude and longitude. The higher resolution data available for California, Nevada, and part of
