The data for this publication total 356 MB on the CD-ROM and 331 MB for this online version. This online version does not include the Acrobat Search index files. It also has a link rather than files for the Adobe Acrobat Reader installer mentioned below. Version 1.0 of the CD-ROM may be purchased for $32 by calling 1-(888) ASK-USGS.

This map and associated digital databases are the result of a compilation and reinterpretation of published and unpublished 1:250,000- and limited 1:125,000- and 1:63,360-scale mapping. The map area covers approximately 416,000 sq km (134,000 sq mi) and encompasses 25 1:250,000-scale quadrangles in central Alaska. The compilation was done as part of the U.S. Geological Survey National Surveys and Analysis project, whose goal is nationwide assemble geologic, geochemical, geophysical, and other data. This map is an early product of an effort that will eventually encompass all of Alaska, and is the result of an agreement with the Alaska Department of Natural Resources, Division of Oil And Gas, to provide data on interior basins in Alaska. A paper version of the three map sheets has been published as USGS Open-File Report 98-133. Two geophysical maps that cover the identical area have been published earlier: "Bouguer gravity map of Interior Alaska" (Meyer and others, 1996); and "Merged aeromagnetic map of Interior Alaska" (Meyer and Saltus, 1995). These two publications are supplied in the "geophys" directory of this report.
