Comments on the geologic information

  • Geologic Description = In 1905, placer mining was reported (Prindle, 1907). Gold is found in the basal stream gravels and on the coal-bearing bedrock (Maddren, 1918). The creek begins in Nenana Gravel and cuts down into the underlying coal-bearing formation (Maddren, 1918).
  • Age = Quaternary placer.
