Location: Placer prospecting and some mining occurred along several miles of Fall Creek (including portions in the Valdez B-3 quadrangle). The map coordinates are about the midpoint of mining in the NW1/4 section 30, T. 5 S., R. 2 E., of the Copper River Meridian. This is locality 87 of Cobb and Matson (1972) and locality 67 of Winkler and others (1981 [OFR 80-892-B]).
Geology: Placer gold, much of which is rounded and coarse, occurs on and in bedrock along Fall Creek and adjacent low benches (Schrader and Spencer, 1901; Moffit, 1918; Mulligan, 1974). About 6 miles of Fall Creek have been prospected, and small amounts of gold were recovered between 1899 and 1916. Bedrock in Fall Creek is greenschist-facies metaflysch of the Late Cretaceous Valdez Group (Winkler and others, 1981 [OFR 80-892-A]). Gold-bearing quartz veins are widespread through the Valdez Group in the southern Valdez quadrangle (Cobb and Matson, 1972).
Workings: Small-scale surface mining and prospecting occurred along Fall Creek between 1898 and 1916 (Cobb, 1979 [OFR 79-1241]).
Age: Holocene.
