Mine and prospect-related symbols, such as those used to represent prospect pits, mines, adits, dumps, tailings, etc., hereafter referred to as “mine” symbols or features, are currently being digitized on a state-by-state basis from the 7.5-minute (1:24,000-scale) and the 15-minute (1:48,000 and 1:62,500-scale) archive of the USGS Historical Topographic Map Collection (HTMC), or acquired from available databases (California and Nevada, 1:24,000-scale only). Compilation of these features is the first phase in capturing accurate locations and general information about features related to mineral resource exploration and extraction across the U.S. To date, the compilation of 693,956 point and polygon mine symbols from approximately 97,060 maps across 46 states and the District of Columbia (DC) has been completed: Alabama (AL), Arizona (AZ), Arkansas (AR), California (CA), Colorado (CO), Connecticut (CT), Delaware (DE), Florida (FL), Georgia (GA), Idaho (ID), Illinois (IL), Indiana (IN), Iowa (IA), Kansas (KS), Kentucky (KY), Louisiana (LA), Maine (ME), Maryland (MD), Massachusetts (MA), Michigan (MI), Minnesota (MN), Mississippi (MS), Missouri (MO), Montana (MT), Nebraska (NE), Nevada (NV), New Hampshire (NH), New Jersey (NJ), New Mexico (NM), North Carolina (NC), North Dakota (ND), Ohio (OH), Oklahoma (OK), Oregon (OR), Pennsylvania (PA), Rhode Island (RI), South Carolina (SC), South Dakota (SD), Tennessee (TN), Texas (TX), Utah (UT), Vermont (VT), Virginia (VA), Washington (WA), Wisconsin (WI), and Wyoming (WY). The process renders not only a more complete picture of exploration and mining in the U.S., but an approximate time line of when these activities occurred. These data may be used for land use planning, assessing abandoned mine lands and mine-related environmental impacts, assessing the value of mineral resources from Federal, State and private lands, and mapping mineralized areas and systems for input into the land management process. These data are presented as three groups of layers based on the scale of the source maps. No reconciliation between the data groups was done." ; dct:identifier "USGS:5a1492c3e4b09fc93dcfd574" ; dct:issued "2025-11-21T12:59:38.453844"^^xsd:dateTime ; dct:modified "20220420"^^xsd:gYear ; dct:publisher ; dct:spatial [ a dct:Location ; locn:geometry "POLYGON ((-124.6951 24.6636, -124.6951 49.3336, -66.9911 49.3336, -66.9911 24.6636, -124.6951 24.6636))"^^gsp:wktLiteral ] ; dct:title "Prospect- and Mine-Related Features from U.S. Geological Survey 7.5- and 15-Minute Topographic Quadrangle Maps of the United States (ver. 7.0, April 2022)" ; dcat:contactPoint [ a vcard:Organization ; vcard:fn "John D Horton" ; vcard:hasEmail ] ; dcat:distribution , ; dcat:keyword "abandoned-mine", "adit", "air-shaft", "alabama-al", "amerigeo", "amerigeoss", "arizona-az", "arkansas-ar", "borrow-pit", "california-ca", "ckan", "colorado-co", "connecticut-ct", "data-services", "delaware-de", "diggings", "district-of-columbia-dc", "dredge-tailings", "evaporation-pond", "florida-fl", "geo", "geographic-information-systems", "geology-geophysics-and-geochemistry-science-center-gggsc", "georgia-ga", "geoscientificinformation", "geospatial-datasets", "geoss", "gravel-pit", "historical-topographic-map-collection-htmc", "hydraulic-mine", "idaho-id", "illinois-il", "indiana-in", "iowa-ia", "kansas-ks", "kentucky-ky", "land-use-and-land-cover", "leach-pond", "linear-prospect", "location", "louisiana-la", "maine-me", "maryland-md", "massachusetts-ma", "michigan-mi", "mill-site", "mine", "mine-drainage", "mine-dump", "mine-shaft", "mine-waste", "mineral-resource", "mineral-resources-program-mrp", "mining-and-quarrying", "mining-hazards", "minnesota-mn", "mississippi-ms", "missouri-mo", "montana-mt", "national", "nebraska-ne", "nevada-nv", "new-hampshire-nh", "new-jersey-nj", "new-mexico-nm", "new-york-ny", "north-america", "north-carolina-nc", "north-dakota-nd", "ohio-oh", "oklahoma-ok", "open-pit-mine", "ore-dump", "ore-stockpile-storage", "oregon-or", "pennsylvania-pa", "placer-mine", "placer-tailings", "prospect-pit", "quarry", "rhode-island-ri", "settling-pond", "south-carolina-sc", "south-dakota-sd", "strip-mine", "tailings", "tennessee-tn", "texas-tx", "tipple", "topographic-map", "topographic-maps", "topoview", "trench", "u-s-geological-survey-usgs", "united-states", "usgs-5a1492c3e4b09fc93dcfd574", "usgs-mineral-deposit-database-usmin", "usgs-quadrangles", "utah-ut", "vermont-vt", "virginia-va", "washington-wa", "west-virginia-wv", "wisconsin-wi", "wyoming-wy" ; dcat:theme <%7Bgeospatial%7D> . a dcat:Distribution ; dct:description "The metadata original format" ; dct:format "XML" ; dct:issued "2022-08-07T03:40:38.539506"^^xsd:dateTime ; dct:modified "2025-11-21T12:59:38.407094"^^xsd:dateTime ; dct:title "Original Metadata" ; dcat:accessURL ; dcat:mediaType "text/xml" . a dcat:Distribution ; dct:description "Landing page for access to the data" ; dct:format "XML" ; dct:issued "2022-08-07T03:40:38.539512"^^xsd:dateTime ; dct:modified "2025-11-21T12:59:38.407533"^^xsd:dateTime ; dct:title "Digital Data" ; dcat:accessURL ; dcat:mediaType "application/http" . a foaf:Agent ; foaf:name "US Migrating" .
