|Location and accuracy||This prospect is nine-tenths of a mile south-southwest of the summit of the Great Nunatak and about one-half mile west of the east lobe of Columbia Glacier. It is at about 1,500 feet elevation in the SE1/4 section 9, T. 9 S., R. 10 W., of the Copper River Meridian. This prospect is probably located to within one-quarter mile. It is locality 85 of Winkler and others (1981 [OFR 80-892-B]).|
Geologic descriptionA lode claim was staked in 1916 for gold (U.S. Bureau of Mines, 1980; Winkler and others, 1981 [OFR 80-892-B]). Bedrock in this area is siliciclastic rocks of the Tertiary Orca Group; the Contact fault that separates the Orca and Valdez Group is about 2 miles to the northeast (Winkler and others, 1981 [OFR 80-892-A]).
