|Location and accuracy||This prospect is 2,100 feet west of peak 3780 and 2.3 miles southeast of the summit of the Great Nunatak; it is at an elevation of about 2,000 feet in the SE1/4 section 14, T. 9 S., R. 10 W., of the Copper River Meridian. This prospect is probably located to within one-quarter mile. It is locality 86 of Winkler and others (1981 [OFR 80-892-B]).|
Geologic descriptionA lode claim was staked in 1968 for gold deposits (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 1.5 miles to the northeast (Winkler and others, 1981 [OFR 80-892-A]).
