Comments on the geologic information

  • Geologic Description = Flat 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]).
  • Age = Tertiary - Quaternary.
