|Location and accuracy||This placer occurrence is at an elevation of about 4,000 feet near the head of an unnamed, southeast-flowing tributary of the Oshetna River, about a mile northeast of Granite Creek. It is near the center of the south boundary of sec. 29, T. 26 N., R. 9 E., Seward Meridian. The location is accurate to within 1/2 mile.|
