This work was supported by the U.S. Geological Survey's Earth MRI program grants G19AC00263, G21AC10326, and G22AC00475.

The data from the Tanana River and Big Delta 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. The Eisen infill block was flown to access the real world impact of tighter line spacing over mountainous terrain of a fixed-wing survey for the benefit of industry partners, DGGS, and the USGS. Portions of the Eisen and Eisen infill block also overlap helicopter based surveys with line spacings of 200 and 400 meters.
