Gridded data (geotiffs.zip) consist of the input isostatic gravity grid as well as grids of Cenozoic basin thickness and bedrock gravity variations and the reduced-to-pole aeromagnetic anomalies.  These grids are provided in geotiff format.  These data and grids supported modeling of gravity and magnetic anomalies to understand the complicated structure beneath this region.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1VPVC5P", "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.69b87639b66b010d8558342d.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_69b87639b66b010d8558342d", "keyword": ["Big Maria Mountains (California)", "Blythe, California", "Dome Rock Mountains (Arizona)", "La Paz County (Arizona)", "Little Chuckwalla Mountains (California)", "Little Maria Mountains (California)", "McCoy Mountains (California)", "Mule Mountains (California)", "Palen Mountains (California)", "Palo Verde Mountains (California)", "Plomosa Mountains (Arizona)", "Quartzsite, Arizona", "Riverside County (California)", "Trigo Mountains (Arizona)", "USGS:69b87639b66b010d8558342d", "farming", "gravity grid", "gravity horizontal gradient maxima", "grid of Cenozoic basin thickness", "grid of bedrock gravity variations", "reduced-to-pole aeromagnetic grid", "residual aeromagnetic horizontal gradient maxima"], "modified": "2026-04-15T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-115.1180, 33.1920, -113.9910, 34.0100", "theme": ["geospatial"], "title": "Geophysical grids, horizontal gradient maxima and depth to bedrock of the Blythe region, California and Arizona"}
