Comments on the geologic information

  • Geologic Description = The only descriptions of this occurrence are references by the U.S. Bureau of Mines (1973) and Dillon (1987) to evidence of placer mining activity and by the location of claims in 1976. The country rocks in the area are shown by DeYoung (1978) to be principally Devonian Hunt Fork Shale and Devonian to Silurian Skajit Limestone with lesser Devonian slate, phyllite, limestone, and siltstone. No descriptive information is available.
  • Age = Quaternary.
