It was compiled from individual 1:250,000-scale geologic \ndata for Washoe County, Nevada, 1:62,500-scale geologic data for the Chilcoot \nand Doyle 15' quadrangles in California and the results of field mapping within the \nstudy area in 2004.  A revised geologic map was needed in the study area because \nthe available published maps have large discrepancies between the reported geologic \nunits along the state line.  The 2004 field mapping was confined to an area approximately \n2000 feet east and west of the California/Nevada state line and about 1.5 miles north \nand south of Dry Valley Creek.  No attempt was made to resolve discrepancies between \nthe published maps in the area outside of the designated mapping area.\nThe discrepancies between geologic units in the previously published maps directly \naffect flow calculations used in the water budget for Dry Valley.  The geologic unit \ninvolved in the greatest discrepancy is a non-welded rhyolitic tuff.  Contacts between \nthis unit and Quaternary basin-fill sediments were refined based on field mapping and \nsampling; and aerial photography.   During mapping, low hills along the southern side \nof the valley floor 0.5 to 1.3 miles east of the state line mapped as Quaternary alluvium \nby previous efforts were recognized as non-welded rhyolitic tuff.  In the locations described \nabove, the non-welded tuff is distinguished by a lag deposit of yellow and red rhyolitic \ngravel at land surface.  In the sub-surface, reached by digging, the tuff is weathered to \na dense clay.  Outcrops of the tuff with faint bedding planes were located in washes.  \nSample points, outcrops, and contacts between the tuff and unconsolidated sediments \nwere located in the field using a handheld Garmin GPS unit (model GPS76).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9GUOEJY", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.858c5125-a349-4ca3-8b41-0c984b93cc92.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_858c5125-a349-4ca3-8b41-0c984b93cc92", "keyword": ["Dry Valley", "USGS:858c5125-a349-4ca3-8b41-0c984b93cc92", "east-central California", "geologic data", "geology", "west-central Nevada"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-120.036502, 39.890238, -119.723631, 40.069531", "theme": ["geospatial"], "title": "1:250,000-scale geology of the Dry Valley Hydrographic Area, Nevada and California"}
