The survey is adjacent to the Aniak, Beaver Creek, and Southern Dishna River geophysical surveys. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from August to September 2010. A total of 6,223.8 line kilometers were collected covering 2,244.5 square kilometers. Line spacing was 400 meters (m).
