The\nEarly Cretaceous-age Antlers Sandstone is an important source of\nwater in an area that underlies about 4,400-square miles of all\nor part of Atoka, Bryan, Carter, Choctaw, Johnston, Love,\nMarshall, McCurtain, and Pushmataha Counties. The Antlers\naquifer consists of sand, clay, conglomerate, and limestone in\nthe outcrop area. The upper part of the Antlers aquifer consists\nof beds of sand, poorly cemented sandstone, sandy shale, silt,\nand clay. The Antlers aquifer is unconfined where it outcrops in\nabout an 1,800-square-mile area.\n\t\t\nThe water-level elevation contours were digitized from a mylar\nmap at a scale of 1:250,000 that was used to prepare a final map\npublished at a scale of 1:500,000 in a ground-water modeling\nreport. Water levels measured in wells in 1970 were used to\nconstruct the map. The water-level elevation contours for the\nAntlers aquifer in Texas are not included in this data set. The\ndigital data set contains water-level elevations that range from\n300 feet (in the east) to 900 feet (in the west) above sea level\nor the National Geodetic Vertical Datum of 1929.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9JTI6NT", "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.ded3ed9e-5544-431f-a9ca-ee6add180b5f.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_ded3ed9e-5544-431f-a9ca-ee6add180b5f", "keyword": ["Antlers Sandstone", "Antlers aquifer", "USGS:ded3ed9e-5544-431f-a9ca-ee6add180b5f", "aquifers", "environment", "geoscientificInformation", "ground water", "ground-water level elevation", "ground-water level elevation contours", "ground-water levels", "ground-water vulnerability", "groundwater", "groundwater level elevation", "groundwater level elevation contours", "groundwater levels", "groundwater vulnerability", "inlandWaters", "water level contours", "water level elevation", "water level elevation contours", "water levels", "water-level contours", "water-level elevation", "water-level elevation contours"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-97.4734, 33.7230, -94.4690, 34.3487", "theme": ["geospatial"], "title": "Digital data sets that describe aquifer characteristics of the Antlers aquifer in southeastern Oklahoma"}
