Magnetic and radiometric data were collected with a fixed-wing aircraft May 24 to June 27, 2021 by MPX Geophysics LTD. A total of 26,926 line kilometers were collected covering 9,731 square kilometers. The magnetometer was mounted to a rear-facing fixed boom (tail stinger). The radiometric crystals were located in the cabin of the aircraft. The Eagle survey was flown with a line spacing of 400 meters (m) and a mean ground clearance of 330 m. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30755.The data from the Eagle airborne magnetic and radiometric geophysical survey will be used for improving the understanding of the geology and mineral potential, promoting resource exploration, and be a part of the continuous regional magnetic data coverage of the Yukon Tanana Uplands.>ascii_data: ASCII format line data, other ASCII data\t\r\n>databases_geosoft: Geosoft format database of line data, other Geosoft format databases\t\r\n>documents: Project and field reports, survey background information, gridded data explanations, other supporting documentation\t\r\n>grids_ermapper: Geographically registered gridded data, ER Mapper ERS format\t\r\n>grids_geosoft: Geosoft-format binary grids, these grids can be viewed in ESRI ArcMap using a free plugin from Geosoft or using the free viewer available from Geosoft\t\r\n>images_registered: GeoTiff format images of all gridded data\t\r\n>kmz: Keyhole markup language (kml) kmz archive files of project data.
