White Mountains Geophysical Survey

The White Mountains airborne magnetic and radiometric geophysical survey covers parts of the Livengood, Circle, and Fairbanks quadrangles 25 kilometers north of Fairbanks, Alaska. Magnetic and radiometric data were collected with a fixed-wing aircraft June 30 to August 22, 2021 by MPX Geophysics LTD. A total of 36,933 line kilometers were collected covering 13,423 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 White Mountains survey was flown with a line spacing of 400 meters (m) and a mean ground clearance of 270 m.
