|Location and accuracy||This placer prospect is about 3 miles above the mouth of Spring Creek, and about 1 mile below a hot spring. The site is in section 25, T. 1 S., R. 13 W., of the Kateel River Meridian. Cobb, 1972 (MF-389), location 43.|
Geologic descriptionSpring Creek heads in the Late Cretaceous Granite Mountain monzonite pluton and flows across its contact with Jurassic-Cretaceous andesitic volcanic rocks. Placer gold reportedly was mined about a mile below a hot spring. Depth to bedrock at the mouth of creek is about 10 feet. Some of the bench placer ground is 12 feet deep.
