Location: The Denali Bench gold placer is on the south bank of lower Valdez Creek, about 0.3 mile east-southeast of the town of Denali. The map site is in the SE1/4 of sec. 13, T. 20 S., R. 1 E., of the Fairbanks Meridian. This location is accurate to within 200 feet.
Geology: The Denali Bench gravels, as defined by Smith (1971), are on the south side of Valdez Creek upstream from the Dry Creek Cut (HE195). The gravels occur both on the bedrock bench and in a paleochannel. The paleochannel contains large, rounded boulders; it grades upwards into well-bedded fluvial gravels. All lithologies in the gravels appear to have been derived from within the Valdez Creek valley.
Workings: Small-scale mechanical and hydraulic operations have tested the tenor of the exposed gravels. Some drilling has been completed on portions of the bench gravels.
Age: Quaternary.
Reserves: There is a large resource of sub-economic gold-bearing gravels.
