Comments on the geologic information

  • Geologic Description = Placer gold was noted in Clearwater Creek during the early 20th Century (Brown, 1926; Andrews, 1978). Anomalous gold in stream sediments was noted during AMRAP investigation (King and others, 1983). The placer gold occurrence is found in a second order stream near its intersection with a third order trunk of Clearwater Creek.
