Creek falls approximately 200 feet in headwater mile.
Location: This occurrence is at an elevation of about 600 feet in the headwaters of an unnamed tributary of Duck Creek, about 1.4 miles south of Clem Mountain. The map site is in section 34, T. 7 N., R. 13 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 21.
Geology: This occurrence consists of Upper Cretaceous-Lower Tertiary granite that may contain uranium-bearing minerals. Uranothorianite was found in a concentrate sample of stream gravels (Gault and others, 1953). The sample contained 0.106% eU.
Workings: In 1947 the U.S. Geological Survey sampled the creek sediment to evaluate its radioactive mineral content (Gault and others, 1953).
Age: Late Cretaceous.

Commodities (Major) - Radioactive minerals
Development Status: None
Deposit Model: Uranothorianite in stream sediments.
