Comments on the geologic information

  • Geologic Description = Auriferous gravel were mined on benches 60-100 feet above stream level. Bench deposits represent pre-glacial creek valley. Gold in stream placers derived from local bedrock and reconcentrated from bench deposits. Gold occurs on or in upper foot or so of slate bedrock. Depth to bedrock averages 14 ft.; Ganes Creek pirated the upper part of Beaver Creek; all gold is below point of capture.
  • Age = Tertiary/Quaternary
