The digital data below was produced from airborne geophysical surveys conducted in 2008 for the Slate Creek-Slana River survey area in the Chistochina mining district, south-central Alaska. Aeromagnetic and electromagnetic (EM) data were acquired by helicopter for about 442 sq miles. Fugro Airborne Survey's frequency-domain DIGHEM V system was used for the EM data. GPR 2009-1 includes (1) raw and processed linedata; (2) gridded data; (3) vector files of data contours and flight lines; and (4) maps of the data.
