Comments on the geologic information

  • Geologic Description = Whereas most of the placer mining along the Bettles River has been on its tributaries, Reed (1938) documented drift mining along the Bettles River from just below Garnet Creek to the mouth of Mule Creek. The depth to bedrock was 14 to 16 feet and the ground apparently ran about $0.50 per square foot of bedrock (1937). The U.S. Bureau of Mines (1973) also showed that there is evidence of placer mining along the Bettles River as far up as the mouth of Mule Creek.
  • Age = Quaternary.
