|Location and accuracy||Grouse Creek probably is now called Moore Creek, a northwest-flowing, 2-mile-long tributary of Woodchopper Creek (Brooks, 1907; Cobb, 1976 [OFR 76-632]). It joins Woodchopper Creek in the southwest corner of T. 6 N., R. 21 E., of the Fairbanks Meridian. The exact location of prospecting on the creek is unknown. Coordinates given are for the approximate midpoint of Moore Creek in section 36, T. 6 N., R. 21 E., of the Fairbanks Meridian. If Moore Creek is Grouse Creek, then the location is accurate to within one mile.|
Geologic descriptionBrooks reported gold prospects along Grouse Creek in 1906 (1907). It may now be called Moore Creek (Cobb, 1976 [OFR 76-632]). The bedrock geology in the Moore Creek area is composed of Upper Devonian(?) conglomerate, which contains pebble- to boulder-size clasts of quartzite and multicolored chert, as well as interbedded quartz-chert-arenite and wacke. This unit has been mapped as the Step Conglomerate (Dover and Miyaoka, 1988).
