Basin Studies

  • Interior Basin Studies

    The State of Alaska and the U.S. Geological Survey, in a cooperative effort, have compiled all of the geological and geophysical data for the interior of Alaska at a scale of 1:500,000. These data are available both in digital form as well as map form. The compiled data consist of the total-intensity magnetic-anomaly, the complete Bouguer Anomaly and the mapped geology, and cover the major interior basins of Alaska. The limits of data coverage are from 61 to 66 latitude and 144 to 159 longitude.

    The gravity, magnetic and geologic maps are now available (Maps GP-1016, GP-1014 and OFR 98-133, respectively). Paper maps can be obtained from the USGS. The digital data (OFR 98-133A) have been compiled on a CD and are also available from the USGS.
