Book Description
San Clemente Island has been studied to determine the geologic suitability of employing the island as a candidate site for the construction of a Rock-Site I installation, the land-linked experimental laboratory. The studies of the island consisted of a review of the geologic literature, aerial reconnaissance, geologic mapping, core drilling, borehole pumping, and offshore geophysical studies and sampling operations. Based on the results of these investigations the recommendation is made that the laboratory area beneath the sea floor be located off Mail Point with access tunnels to the laboratory originating at either Mail Point or Lost Point. As a candidate site, San Clemente Island is considered to be feasible but difficult. (Author).

Book Description
A 1,200-foot core hole drilled near Eel Point on the west coast of San Clemente Island, California, penetrated a homogeneous series of andesite flows varying in thickness from 11 to 169 feet. Petrographic examination revealed that textural variations within flows as a result of different cooling rates are more distinct than differences in composition between individual flows. Potassium-argon dates indicate that these flows were extruded in less than one-half million years during Miocene time. The flows are inferred to dip seaward at between 10 and 30 degrees. The rock will provide sound material for excavation. Problems of water leakage can be expected at faults and zones of decomposed rock. (Author).
