This digital raster dataset represents depth to pre-Cenozoic bedrock in northern Nevada as published in Chapter 6: Geophysical Methods and Application in U.S. Geological Survey Bulletin 2218, Assessment of Metallic and Mineral Resources in the Humboldt River Basin, Northern Nevada by D.A. Ponce. The data are represented on figure 6-9 in this publication and were later provided as raster format geospatial digital data via written communication from D.A. Ponce in 2007. The data have been reprojected but are otherwise as provided. A thorough explanation of the production methods is available in the larger work.
Raster grids depicting the current knowledge for elevation for the bedrock surface, pre-Mesozoic surface, the Precambrian surface and the basement surface based on the addition of new data from completed mapping. Basement is the top of structurally complex Precambrian rocks where the Phanerozoic and Proterozoic basins are removed based on geophysical modeling and drill hole interpretation. Statewide elevation datasets are stored as contoured line files and attributed with publication source, contour elevation and date and time of last edit. New raster grids are generated with the 'Topo to Raster' tool in ESRI ArcMap 10.7. 6/2023 Update: The 2023 version of rasters are currently not available online to download but...
