DENA preserves\nover 6 million acres of wild land that provides opportunities\nfor recreation, subsistence hunting and gathering, preservation of\ncultural resources, and scientific research.  Despite its size and\npopularity, DENA has only one road\u00e2\u0080\u0094the dead-end, 92-mile Denali National\nPark Road (hereafter referred to as the Park Road). The Park Road is\nmostly gravel; only the first 15 miles are paved. It is the only access\nfor most DENA infrastructure, including visitor centers, staff facilities,\ncampgrounds, and businesses.\nThe Park Road crosses a steep, constantly changing landscape, shaped by\nactively deforming and uplifted bedrock, glacier and meltwater erosion,\nand various permafrost processes. Geologic hazards (geohazards) such as\nrockfall, debris flows, and landslides cause significant damage to the Park\nRoad every year, requiring periodic closure, and costing millions of\ndollars in repair and maintenance.  For the first time in the park\u00e2\u0080\u0099s\nhistory, the Park Road is closed near its midpoint for an entire season\ndue to displacement caused by the Pretty Rocks rock glacier and landslide\ncomplex.  In addition, DENA is situated along a major fault system and\nexperiences numerous earthquakes every year.  Most are too weak to be felt,\nbut a 7.9 magnitude earthquake shook the region in 2002, and at least one\nmajor landslide, which formed Bergh Lake along the Park Road corridor, was\ncaused by seismic shaking in 1953.\nIn response to the threat posed by geohazards, the U.S. Geological Survey\n(USGS) and the National Park Service (NPS) have partnered to produce a new,\nhigh-resolution geologic map to help identify basin sediments and bedrock\ngeology, active faults, unstable slopes, and hazardous geologic substrates\nalong the Park Road corridor and other areas that contain administrative\ninfrastructure.  This new geologic map augments previous broad scale,\nbedrock-focused maps and uses detailed, updated imagery and elevation data\nto provide a digital framework for future research, hazard identification,\nand infrastructural development.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9W76PSM", "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.63a1fe97d34e0de3a1f27d0a.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_63a1fe97d34e0de3a1f27d0a", "keyword": ["Alaska", "Alaska Range", "Browne glaciation", "Cantwell Basin", "Cantwell Formation", "Cretaceous", "Denali", "Denali National Park", "Denali Park Road", "Denali fault system", "Devonian", "Dry Creek glaciation", "East Fork Toklat River", "Eilson Visitor Center", "Eocene", "Fang Mountain", "Geologic Map", "Healy glaciation", "Highway Pass", "Hines Creek", "Hines Creek fault", "Holocene", "Holocene to latest Pleistocene", "Jurassic", "Kantishna Hills", "McKinley River", "Miocene", "Mount Galen", "Mount Healy", "Mount Margaret", "Mount Wright", "Muldrow glacier", "Nenana Gravel", "Nenana River", "Oligocene", "Paleocene", "Park Road fault", "Pennsylvanian", "Plains of Murie", "Pleistocene", "Pliocene", "Polychrome Pass", "Pretty Rocks", "Quaternary", "Quaternary deposits", "Riley Creek glaciation", "Sable Pass", "Sanctuary River", "Savage River", "Stony Pass", "Surficial Geology", "Teklanika Formation", "Teklanika River", "Teklanika volcanics", "Toklat River", "Triassic", "USA", "USGS:63a1fe97d34e0de3a1f27d0a", "United States", "Usibelli Group", "Wonder Lake", "early Pleistocene", "landslides", "late Pleistocene", "latest Holocene to middle Holocene", "latest Pleistocene", "middle Pleistocene", "neotectonics", "permafrost"], "modified": "2023-02-06T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-151.10340, 63.371300, -148.84600, 63.776800", "theme": ["geospatial"], "title": "Data release for the Geologic Map of the Denali Park Road Corridor, Denali National Park, Alaska"}
