Comments on the geologic information

  • Geologic Description = The bedrock of this placer deposit is early to mid-Paleozoic schist (Cobb and others, 1981). Depth to bedrock is 5 to 6 feet in the stream bed and 8 to 9 feet in areas adjacent to the stream bed. Gravel is pebble- to cobble-sized material, and a few boulders. Four holes were sunk to bedrock at the bend of the creek (Reed, 1932). The gold reportedly is fine and flaky.
  • Age = Quaternary.
