This index supplements a similar index of published reports (Cobb, 1973) currently being processed for formal publication. Inasmuch as many open-file reports are preliminary and eventually superseded by final published reports, it is inappropriate to include references to open-file reports in a permanent index. As most preliminary reports are of immediate, although temporary, value, it is desirable that references to them be compiled and made available for general use through the medium of open-file release. This index is designed to fill that need.

Geologic mapping of the Port Moller, Stepovak Bay, and Simeonof Island quadrangles was begun under the auspices of the Alaska Mineral Resource Assessment Program (AMRAP) in 1983 . Two important mineral deposits are located in the Port Moller quadrangle; the Pyramid prospect is the largest copper porphyry system in the Aleutian Arc, and the Apollo Mine is the only gold mine to reach production status in the Aleutian Arc.
