East Styx Geophysical Survey

The digital data below was produced from airborne geophysical surveys conducted in 2013 and 2014 for the Farewell survey area in the McGrath and Yentna mining districts, Talkeetna, Tyonek, McGrath, and Lime Hills quadrangles, south-central Alaska. Aeromagnetic, electromagnetic (EM), and radiometric data were acquired by helicopter for about 1060 sq miles. CGG's frequency-domain DIGHEM V system was used for the EM data. This dataset includes (1) raw and processed linedata; (2) gridded, Google Earth, and Geotiff formats of the calculated linedata; (3) maps of the data and flight lines; and (4) vector files of data contours and flight lines.
