| Location and accuracy | This prospect is about 1,500 feet west of the lower Nabesna Glacier on the east flank of hill 4040. It is at an elevation of about 3,500 feet in the NW1/4 of section 36, T. 5 N., R. 13 E. of the Copper River Meridian. This is National Park Service locality WRST-25 (unpublished data) and the coordinates for this prospect were provided by the National Park Service. |
Geologic descriptionAn unpublished National Park Service map and accompanying database identify this locality as a gold, copper, and iron prospect.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). | |
