The spatial databases represent the original content of 43 published geologic maps, provide normalized map unit descriptions, and provide additional information and interpretation not in the original reports.

Mathematical analysis of gravity and aeromagnetic data, with basic and derived grids and vector data and maps.

Magnetic susceptibility measured for 700 samples of drill core from thirteen drill holes in the porphyry copper-molybdenum deposit of the Stinkingwater mining district in the Absaroka Mountains, Wyoming

Grids of total magnetic intensity for the park

Geologic map unit and lithologic descriptions used in Open File Report 2005-1235, with extensive bibliographic references to geologic literature that could not be included in the spatial database.

Airborne electromagnetic and magnetic survey data were collected during 2016 along 4,212 line-kilometers over this area. The survey was flown with a nominal line spacing of 450 meters or less, and mean flight height about 48 m providing depth of investigation about 500m. Data are provided in CSV format, flight lines in shapefile format.

Airborne electromagnetic (AEM) and magnetic survey data were collected in 2016 along 4,212 line-kilometers over this area as part of a study of the subsurface geologic structure and geothermal and groundwater resources of Yellowstone National Park. Data are provided in CSV format.
