Iron Creek Geophysical Survey

The digital data below was produced from airborne geophysical surveys conducted in 1997 for the Iron Creek survey area in the Talkeetna Mountains Quadrangle. Many of the files for this release were published on paper and available by mail order beginning in 1998. This updated data release provides a compilation of the previously published paper files (in PDF format) and the originating data files that were acquired from the contractor. The airborne data were acquired and processed under contract between the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (DGGS), and WGM, Inc. Geoterrex-Dighem, the subcontractor, acquired and processed the data in 1997 and 1998.

  • GPR 2014-6. Iron Creek airborne electromagnetic and magnetic geophysical survey data compilation. This publication consolidates the data, grids, vectors, project report and interpretation, and most of the maps published in 1998 by DGGS. The original EM anomalies, now in digital format, and new analytic signal and calculated 1VD grids have been added to this publication. Another improvement is reformatting the linedata to ascii Geosoft XYZ format. The previous publications included the data in line and gridded format (PDF 98-7) and project report and interpretation (PDF 98-9). This publication also incorporates and consolidates material from PDFs 98-1 through 98-6, 98-8; 98-18A through G; and RIs 98-1 through 98-3. The prior publications were authored by L.E. Burns, Geoterrex-Dighem, WGM Inc., R.A. Pritchard, S.A. Liss, and DGGS Staff.
