Description:

Abstract:: This data contains placer district boundaries. Districts refer to the name of a group of geologically and geographically related placer deposits, as derived from published sources or from general usage. Economic and significant heavy metals are reported for each district.
Purpose:: This digital data was created for mapping. This data was originally used in conjunction with the State Land Selections Project.
Supplemental_Information:: Procedures_Used: Data was digitized from 1:5000000 map contained in U.S. Geological Survey Bulletin 1786, Plate #2, Location of Significant Metalliferous Placer Districts of Alaska.
Project: State Land Selections Date Received: July 16 1991 Verified: Richard McMahon 7/16/91 Documented: " " "
