|Location and accuracy||This occurrence is at an elevation of about 2750 feet near the south end of the ridge separating Rainy Creek and Dry Creek. It is in the NE1/4 NW1/4 section 22, T. 16 S., R 17 W., Fairbanks Meridian. The location is accurate.|
This occurrence is a nearly vertical quartz vein exposed over a distance of about 1/2 mile on the east side of Rainy Creek. The vein strikes NE and cuts upper Precambrian Birch Creek Schist (Bundtzen, 1981; Hawley and Associates, 1978, fig. 4.1-A(1)); Thornsberry, McKee, and Salisbury, 1984).The vein consists mainly of quartz; it is resistant and crops out locally. There are no published reports of any metalliferous minerals in the vein. A placer deposit in Rainy Creek below this site suggests that the vein locally contains free gold.
