|Location and accuracy||This placer prospect is near the intersection of Rock Creek and a tractor trail marked on the Candle B-5 map. The site is about a mile above the mouth of the creek, in section 12, T. 1 S., R. 12 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 35.|
Geologic descriptionRock Creek probably was prospected for placer gold in the early 1900s. Uranothorianite was identified in placer concentrates collected in 1947 by the U.S. Geological Survey (Gault and others, 1953).
