Location and accuracy Winkler and others (1981, locality 72 [OFR 80-892-B]) indicated placer prospecting for about 1.8 miles of lower Ernestine Creek between the elevations of 1,750 and 2,000 feet. The map site is the approximate midpoint of this placer prospect. It is in the SE1/4 section 20, T. 5 S., R. 2 E., of the Copper River Meridian.

Geologic setting

Geologic description

Placer gold occurs in shallow gravels of Ernestine Creek (Rohn, 1900; Winkler and others, 1981 [OFR 80-892-B]). The deposits are probably on bedrock and similar to those on Fall Creek (VA073). Bedrock in vicinity of Ernestine Creek is greenschist-facies metaflysch of the Late Cretaceous Valdez Group (Winkler and others, 1981 [OFR 80-892-B]). Gold-bearing quartz veins are widespread through the Valdez Group in the southern Valdez quadrangle (Cobb and Matson, 1972).
