Valdez Creek Geophysical Survey

This geophysical survey is located in central Alaska in the Valdez Creek mining district in the south-central Alaska Range. It is about 180 kilometers south of Fairbanks, Alaska and about 250 kilometers northeast of Anchorage, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEM system from August to September 1993. A total of 594 line kilometers were collected covering 210.5 square kilometers. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line.
