Ridge, San Clemente Island , California, W. E. Greenwell, 1860; S. Forney, 1878.—On the northern end of a conspicuous black ridge, near the head of the little valley running south from the anchorage at Wilsons Cove, and to the left coming up the valley. (Note 3, p. 615, except a leaden bolt alone marked the center in the underground stone.) In 1878 the old reference stubs to the north south, east, and west were found and left undisturbed.
