A famous Alaska mineral locality known since the early 1900's that has long been mined for garnet specimens. Mine site is at an elevation of from about 50 to 200 feet and about 1000 feet from the shoreline in the north-central portion of section 19, T 61 S, R 83 E.; it can be reached by a well marked trail along Garnet Creek from a landing on the Stikine River. Currently (1998) the property is owned by the Boy Scouts in Wrangell and permission to enter it should be obtained from them. (USGS MRDS)
