The Kuskokwim airborne magnetic and radiometric survey, northern Kuskokwim Mountains geophysical survey covers parts of the Tanana, Norton Bay, Nulato, Ruby, Kantishna River, Medfra, and Mt. McKinley quadrangles west of Nenana, Alaska. Magnetic and radiometric data were collected with a fixed-wing aircraft May 14 to August 31, 2023, by MPX Geophysics LTD. The survey contains a single block. A total of 86,712 line-kilometers were collected. The block covers 29,361 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 block was flown with a line spacing of 400 meters (m). The mean ground clearance is 184 meters.
