Comments on the geologic information

  • Geologic Description = Smith (1933) reports on-going placer mining at this location in 1931, however, no deposit description for this site is available. Most likely it is a bench deposit similar to the Pleistocene age Cache Creek deposits (TL029). Bedrock is Tertiary sedimentary rocks of the Kenai Group (Reed and Nelson, 1980). Clark and Hawley (1968, p.45) report the gold fineness as 869 1/4.
  • Age = Pleistocene.
