For Reference Only At Bureau Libraries, 1973; :1-153
Subject overlays for the 153 quadrangles of Alaska are clear plastic sheets with numbered circles showing the locations of all mineral deposits recorded in the state of Alaska kardex files of mineral claim data. Identically numbered tables on the right margin show number of claims, lode or placer patented or unpatented, and principal minerals. These overlays have been prepared for the resource planning team of the joint Federal-State Land Use Planning Commission. They are also basic data for the Bureau of Mines minerals availability system.
