1:250,000-scale geology of the Dry Valley Hydrographic Area, Nevada and California

This dataset consists of digital geologic data for the Dry Valley Hydrographic area, Nevada and California. It was compiled from individual 1:250,000-scale geologic data for Washoe County, Nevada, 1:62,500-scale geologic data for the Chilcoot and Doyle 15' quadrangles in California and the results of field mapping within the study area in 2004. A revised geologic map was needed in the study area because the available published maps have large discrepancies between the reported geologic units along the state line. The 2004 field mapping was confined to an area approximately 2000 feet east and west of the California/Nevada state line and about 1.5 miles north and south of Dry Valley Creek. No attempt was made to resolve discrepancies [...]
