|Location and accuracy||Flat Creek is a tributary of the Charley River; their confluence is in T. 4 N., R. 24 E., of the Fairbanks Meridian. Flat Creek is about 10 miles long. The exact location of placer mining along Flat Creek is not known. Coordinates have been arbitrarily placed at the approximate midpoint of the creek in section 18, T. 3 N., R. 25 E., of the Fairbanks Meridian. The location is accurate to within 10 miles.|
Geologic descriptionFlat Creek was reported as a placer gold prospect in 1915 by Brooks (1915). The bedrock in the upper half of Flat Creek is Precambrian or Paleozoic, medium- to high-grade pelitic schist; the lower half is underlain by Cretaceous to Tertiary sedimentary rocks (Dover and Miyaoka, 1988). The likely source of gold in other creeks in the area (Fourth of July Creek (CY015), Coal Creek (CY006), and Woodchopper Creek (CY038)) is the Tertiary conglomerate (Cobb, 1976 [OFR 76-632]).
