Summary

We present a numeric grid containing estimates of the depth to the pre-Cenozoic basement for the western United States. Values for these grids were combined and integrated from previous studies or derived directly from gravity analyses. The grids are provided with 1-km grid-node spacing in WGS84 latitude-longitude coordinates. Detailed information regarding the derivation of these estimates is provided by Shah, A.K. and Boyd, O.S., 2018, Depth to basement and thickness of unconsolidated sediments for the western United States - Initial estimates for layers of the U.S. Geological Survey National Crustal Model: U.S. Geological Survey Open-File Report 2018-1115, https://doi.org/10.3133/ofr20181115.

Purpose

This grid was compiled as a component of the USGS National Crustal Model, which was designed to assist estimation of site-specific responses to earthquakes on a regional scale. It may also have use for regional studies in other subject areas such as geologic mapping, hydrology, and natural resource evaluation.
