Location: The coordinates are for Van Curlers Bar along the Middle Fork of the Chena River. Placer claims extend along the Middle Fork of the Chena River from about 145 00 00 to 145 35 00 W long., but most mining was at or near this location.
Geology: The bedrock immediately beneath the Van Curlers Bar is described by Foster and others (1983) as phyllite, calcareous phyllite and marble. The headwaters of the Middle Fork of the Chena River, however, are underlain by pelitic schist. Placer gold mining activity was reported in 1912, 1921, and 1927 to 1940, and various mining and/or prospecting occurred up to 1981 (Menzie and others, 1983). A small dredge operation resulted in moderate production for many years prior to 1963, but details are lacking (Cobb, 1973, p. 129, [B 1374]).
