Comments on the geologic information

  • Geologic Description = Timberline Creek drains an area underlain by phyllite and argillite intruded by small, Upper Cretaceous diorite stocks. A small amount of gold has been recovered from this placer deposit. The best values occur in a channel in the prograde delta where Timberline Creek exits its valley just above Valdez Creek. The placer gold was derived from the many small lode gold occurrences in the drainage basin (HE199, HE200, HE201, HE202, and HE203).
  • Age = Holocene. The gold placer was probably formed after the last phase of glaciation.
