Seal, San Clemente Island , California, William E. Greenwell, 1862; Stehman Forney, 1878.—About 400 meters from the extreme south point of the island, known as China Point, on the top of the island and highest of four small hillocks directly north of a small rocky island off the south end of the point. In 1862 the station was marked by a drill hole in a large, fixed rock. In 1878 a leaden bolt and copper nail were driven into this hole, the nail marking the center of the station. Three drill holes in the fixed rock were made as reference marks; to the south, 3.3 feet; to the east, 3.6 feet; and to the west, 4.1 feet.[[Annual Report of the Director, U.S. Coast & Geodetic Survey, 1904]
