Location and accuracy Myrtle Creek is a tributary of the Clearwater Fork of the Toklat River. Myrtle Creek has two main forks: the west fork rises below Spruce Creek; the east fork rises below Kankone Creek. The placer prospect is in the central part of the creek, about halfway between the main tributary forks. It is in the SE1/4 section 26, T. 15 S., R. 16 W., Fairbanks Meridian.

Geologic setting

Geologic description

The west fork of Myrtle Creek below Spruce Creek has an extensive upper basin of undivided terrace and other gravels; the east fork has some alluvial gravel in its upper basin (Levell, 1984, v. 2). Both east and west forks flow through bedrock canyons cut into the Birch Creek Schist before they join the Clearwater to form a broad alluvial valley.
Myrtle Creek probably was prospected for placer gold in the early years of the Kantishna district, and may have been mined on a small scale. In 1983, thirteen sluice samples from the main creek and its two main tributaries contained at least a trace of gold (Levell, 1984, v. 2). Three of the samples contained more than 0.001 ounce of gold per cubic yard and one contained 0.0121 ounce of gold per cubic yard. The highest grade sample came from the fork that drains Kankone Peak.
Myrtle Creek drains an area of numerous lode mineral deposits. A stream- sediment sample from the tributary fork below Spruce Peak contained 2 ppm silver, and a sediment sample from the main stem of Myrtle Creek between the two main forks contained 65 ppm antimony (Bundtzen, Smith, and Tosdal, 1976).
