  • Aero magnetic data over the Hiawatha crater

    Aero magnetic data often shows impact craters very well. Did you ever look at the airborne magnetic geophysical data that seems to end at the borders of the crater?
    Usually the aircraft keeps gathers data well past the edge of the published map and this “extra data” may show some evidence of the crater. This data may be available from GEUS or you could hire the contractor to reconstruct that data.
    I believe this data was gathered by Sander Geophysics but you would need to check.
