Geologic setting

Geologic description

An unpublished National Park Service map and accompanying database identify this locality as a gold, copper, and iron prospect. One mining claim was located between 1959 and 1972. This prospect is in an area where porphyry dikes cut Triassic, Nikolai Greenstone (Richter, 1973). Massive magnetite with pyrite and some chalcopyrite occurs in Nikolai Greenstone about 1.5 miles to the south (NB040).
