Location: This placer mine is on Timberline Creek, a west-flowing tributary to Valdez Creek. The center of placer mining on Timberline Creek is about 1.2 miles east northeast of Denali. The map site is in the E1/2 of sec. 18, T. 20 S., R. 2 E., of the Fairbanks Meridian. The location is shown as Site 5 in Smith, 1981.
Geology: 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).
Workings: Surface placer mine.
Age: Holocene. The gold placer was probably formed after the last phase of glaciation.
Production: Total production is not known.
