Geologic setting

Geologic description

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.
