Comments on the geologic information

  • Geologic Description = Rocky Creek has been prospected and gold and cinnabar colors have been recovered in pan concentrates. A glacier occupied the pass at the head of Rocky Creek and the stream valley contains outwash deposits. Sedimentary bedrock of the mid-Cretaceous Kuskokwim Group is exposed over large parts of the drainage (Box and others, 1993).
  • Age = Quaternary.
