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, at the north mouth of Davis River. The site is in section 36, T. 70 S., R. 99 E., of the Copper River Meridian. It corresponds to loc. 13 in Elliott and others (1978). The location probably is accurate within 0.2 mile.

Geologic setting

Geologic description

The 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.
