|Location and accuracy||The approximate location of this placer claim, known only from U. S. Bureau of Mines (1977) claim records, is at or near sea level on the west shore of Portland Canal, about 0.3 mile north of the mouth of Davis River. The site is at the boundary of sections 25 and 36, T. 70 S., R. 99 E., of the Copper River Meridian. It corresponds to loc. 12 in Elliott and others (1978). The location is probably accurate within 0.3 mile.|
Geologic descriptionThe country rocks in the area of this site are porphyritic quartz monzonite and granodiorite of the Eocene Davis River Pluton (Smith, 1977; Berg and others, 1988). According to U.S. Bureau of Mines claim records (1977), this placer claim, which appears to be in an area underlain by quartz monzonite or granodiorite, adjacent to a north-northeast-trending, high-angle fault, was staked for Fe. No other information about it has been made public.
