This report contains the Valley-Specific Aggregate Resources Study (VSARS) evaluation for Cave and Steptoe valleys and surrounding areas in Nevada. It is the tenth in a series of reports that contain valley-specific aggregate information on the location and suitability of basin-fill and rock sources for concrete and road-base construction materials. The findings presented are based on field reconnaissance and limited laboratory testing, existing data from the Nevada Department of Highways, previous regional aggregate investigations, and ongoing Verification studies.
