Petersville Mining District Geophysical Survey
The Petersville mining district electromagnetic and magnetic airborne geophysical survey geophysical survey is located approximately 40 kilometers west of Talkeetna, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from October 1 to October 8, 1996. A total of 2967 line kilometers were collected covering 1075 square kilometers (km). Line spacing was 400 meters (m). Data were collected an average of 36 m above the ground surface from a helicopter towed sensor platform ("bird") on a 30 m long line.
