  <dc:description>&lt;p&gt;We present numeric grids containing estimates of the thickness of unconsolidated sediments and depth to the pre-Cenozoic&lt;br&gt;basement for the western United States. Values for these grids were combined and integrated from previous studies or derived&lt;br&gt;directly from gravity analyses. The grids are provided with 1-kilometer grid-node spacing in ScienceBase (https://www.sciencebase.gov).&lt;br&gt;These layers may be updated as results from new studies become available. &lt;/p&gt;</dc:description>
