    Wrangellia survey area: Airborne magnetic and electromagnetic data in line (point), grid, vector, and map formats, Talkeetna Mountains, Healy, and Mt. Hayes quadrangles, south-central Alaska

    Metadata Updated: July 5, 2023

    This digital publication, GPR 2014-1, contains data produced from airborne geophysical surveys conducted in 2013 for the Talkeetna Mountains, Healy, and Mt. Hayes quadrangles in south-central Alaska. The area is in the Valdez Creek and Delta River mining districts. Aeromagnetic and electromagnetic (EM) data were acquired by helicopter for about 1310 sq miles, and additional data donated by Millrock Exploration Corporation, Anchorage, increased coverage by about 12 sq miles. Millrock also provided some infill flight lines for over a similar amount of sq miles. CGG acquired and processed all the airborne geophysical data. The data were all flown with the same systems and contract specifications. CGG's frequency-domain DIGHEM V system was used for the EM data. GPR 2014-1 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; (4) vector files of data contours and flight lines. Supporting files include gpr2014_001_readme.txt, Wrangellia_Linedata.txt, gpr2014_001_browsegraphic.pdf, and individual jpgs of some of the items in the browsegraphic file.
