Depth to pre-Cenozoic bedrock in northern Nevada


Publication Date
Time Period


Ponce, D.A., and Damar, N.A., 2017, Depth to pre-Cenozoic bedrock in northern Nevada: U.S. Geological Survey data release,


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.

This dataset was produced to support a study, done in cooperation with the Bureau of Land Management (BLM), to assess the mineral resource potential of the Humboldt River Basin in northern Nevada. Much of the land in the Humboldt River Basin is publicly owned and administered by the BLM; they requested the study to aid their land-use planning, including the future possible locations of mine dewatering. Dewatering of large open-pit and deep underground mines has modified water tables near those mines, and the water is diverted to agriculture uses, recharged into the aquifers, or discharged directly into the Humboldt River and its tributaries. The assessment used geological, geochemical, geophysical, and mineral-deposit data to predict where undiscovered metallic mineral resources might be present.
