The surface of this basement is defined from three types of control: in the Sierra Nevada from the topography itself, beneath the eastern two thirds of the Great Valley in considerable detail from numerous wells drilled for oil and gas, and beneath the western San Joaquin Valley in less detail from seismic reflection and refraction profiles. Together, these data demonstrate that the surface of crystalline rock is continuous from the exposed rock in the mountains to the top of high-velocity rock buried deep beneath the eastern front of the southern Coast Ranges. Purpose: The main purpose was to explore and document the shape and continuity of the basement surface and to determine the relation of the surface to the tectonic wedge hypothesis (Wentworth and others, 1984; Wentworth and Zoback, 1989).

The compilation was begun as part of the investigation of the 1983 Coalinga earthquake (Wentworth and Zoback, 1990; Yerkes, Levine, and Wentworth, 1990), and was subsequently converted to digital form and extended to the whole of the Great Valley and Sierra Nevada. Completeness_Report: Complete Lineage: Process_Step: Process_Description: The compilation was begun as part of the investigation of the 1983 Coalinga earthquake (Wentworth and Zoback, 1990; Yerkes, Levine, and Wentworth, 1990), and was subsequently converted to digital form and extended to the whole of the Great Valley and Sierra Nevada. The database in its present form was compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute [ESRI], Redlands, California), and is stored in ARC/INFO coverage format (version 6) in a UNIX tar file.
