From Islapedia


Knob, San Clemente Island , California, W. E. Greenwell, 1862; S. Forney, 1878.—On the same ridge as Guds [triangulation], and to the northwest of it, on a small knob on the top of the ridge. The center of the station was marked by a copper nail in a leaden bolt driven into a drill ole in the solid rock. There were two drill holes in the rock, 24 inches each from the station, and in line with it, and 15 feet distant to the north, southeast, and southwest, were three large stones, level with the surface of the ground, with drill holes in the top.
