Location: Dome Creek, which is unnamed on the Bettles B-3 topographic map (1970), is a tributary of the Kanuti River. Its mouth is about 14 miles southwest of Caribou Mountain. Cobb's (1978 [OF78-94]) description of this occurrence indicates considerable uncertainty as to its location. The coordinates above are based on U.S. Bureau of Mines and Bureau of Land Management records that locate the occurrence, but do not indicate the basis on which the location was determined (Bottge, 1986; Kurtak and others, 2002) This occurrence is probably about 0.5 mile east-southeast of the center of section 32, T. 17 N., R. 16 W., of the Fairbanks Meridian. The location is accurate within 2 miles.
Geology: Brooks (1912) reported that placer gold prospects were found on Dome Creek in 1911. There are no other published reports of mining or prospecting on this creek. The U.S. Bureau of Mines investigated the area in the 1980's, apparently for its chrome potential (Foley and McDermott, 1983; Kurtak and others, 2002). Two panned-concentrate samples from Dome Creek, about three miles east of the Kanuti River, contain 2 very fine gold flakes, and 425 and 508 ppm chromium (Kurtak and others, 2002).
Workings: Placer prospecting and some surface sampling.
Age: Quaternary.
