This area encompasses\nthe panhandle counties of Cimarron, Texas, and Beaver, and the\nwestern counties of Harper, Ellis, Woodward, Dewey, and Roger\nMills. The High Plains aquifer underlies approximately 7,000\nsquare miles of Oklahoma and is used extensively for irrigation.\nThe High Plains aquifer is a water-table aquifer and consists\npredominately of the Tertiary-age Ogallala Formation and\noverlying Quaternary-age alluvial and terrace deposits. In some\nareas the aquifer is absent and the underlying Triassic,\nJurassic, or Cretaceous-age rocks are exposed at the surface.\nThese rocks are hydraulically connected with the aquifer in some\nareas.\n\t\t\nThe High Plains aquifer is composed of interbedded sand,\nsiltstone, clay, gravel, thin limestones, and caliche. The\nproportion of various lithological materials changes rapidly\nfrom place to place, but poorly sorted sand and gravel\npredominate. The rocks are poorly to moderately well cemented by\ncalcium carbonate.\n\t\t\nThe aquifer boundaries were constructed by extracting lines from\ndigital surficial geology data sets based on a scale of\n1:125,000 for the panhandle counties and 1:250,000 for the\nwestern counties. Some of the lines were digitized from maps in\na published water-level elevation map for 1980.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9TD2AXI", "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.c44151b8-e182-4296-836f-4bd813725289.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_c44151b8-e182-4296-836f-4bd813725289", "keyword": ["High Plains aquifer", "Ogallala Formation", "Ogallala aquifer", "USGS:c44151b8-e182-4296-836f-4bd813725289", "aquifer boundary", "aquifers", "environment", "geoscientificInformation", "ground water", "ground-water vulnerability", "groundwater", "groundwater vulnerability", "inlandWaters", "northwestern Oklahoma", "panhandle of Oklahoma", "western Oklahoma", "western counties in Oklahoma"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-102.8856, 35.2500, -99.2367, 37.1297", "theme": ["geospatial"], "title": "Digital data sets that describe aquifer characteristics of the High Plains aquifer in western Oklahoma"}
