Summary

Ground-water flow through the region south and west of Frenchman Flat, in the Ash Meadows subbasin of the Death Valley ground-water flow system, is controlled mostly by faults which arrange the distribution of permeable and impermeable rocks. In addition, most permeability is along fractures caused by faulting in carbonate rocks. Large faults are more likely to reach the potentiometric surface as deep as 325 meters below the ground surface and are more likely to effect the flow path than small faults. This study concentrated on identifying large faults, especially where they cut carbonate rocks. Small faults, however, may develop as much permeability as large faults if they are penetrative and are part of an anastomosing fault zone. [...]

Purpose

The purpose of this study is to identify the overall pattern of faults and joints at the ground surface in the Spotted and Specter Ranges which will be an indication of the fracture system at the depth of the water table. This will subsequently indicate the ground-water flow path.
