Geologic setting

Geologic description

About 6 miles of upper Manker Creek were shown by Winkler, Miller, and others (1981 [OFR 80-892-B], locality 113) as a placer gold prospect. Gold was reported to be present on Manker Creek as early as 1900 (Schrader, 1900, p. 422) and placer claims have been staked in this area (U.S. Bureau of Mines, 1980). Bedrock in the Manker Creek drainage includes metavolcanic and metasedimentary rocks of the McHugh Complex and metasedimentary rocks of the Valdez Group (Winkler and others, 1981 [OFR 80-892-A]). The Valdez Group hosts many gold-bearing quartz veins in the southern Valdez quadrangle.
