Abstract
A reconnaissance mineralogical and geochemical survey of stream sediments in the Healy quadrangle was conducted during 1980-1982 as part of the Alaskan Mineral Resource Assessment Program (AMRAP) of the United States Geological Survey (USGS). As a result of the various AMRAP investigations, a mineral resource evaluation of the quadrangle was published by Cox and others (1989). The Healy quadrangle comprises 6,700 mi2 in southern Alaska and is located 60 mi south of Fairbanks and 120 mi north of Anchorage. The quadrangle is traversed by the central Alaska Range, which forms a glacially sculptured arcuate mountain wall with a maximum elevation of 12,339 ft (Mt. Deborah). The lowest elevation is about 1,000 ft along the Nenana River. Access to the sample sites was provided by helicopters, with the exception of a few sites that were accessible by automobile from the Denali and George Park highways.
