Thickness of unconsolidated sediments for the USGS National Crustal Model We present a numeric grid containing estimates of the thickness of unconsolidated sediments 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.

The release includes location information for seismic reflection and airborne electromagnetic (AEM) data over Crowleys Ridge, a table of topographic metrics derived from analysis of the 10m National Elevation Dataset (NED) digital elevation model (DEM), a shapefile of scarps mapped on a 1m bare-earth lidar DEM, and a shapefile of a revised New Madrid seismic zone fault network interpretation. These datasets are associated with the publication: Thompson Jobe, J.A., Gold, R.D., Briggs, R.W., Williams, R.A., Stephenson, W.J., Delano, J.E., Shah, A.K., Minsley, B.J.,...
