    * California, as a joint WSI-3311HH expedition, which enabled the director to survey archeological sites, caves and evidence of higher sea stands related to the work carried out on the Santa Barbara Channel Islands, and Lake La-hontan. We boarded the 83 foot up the Gulf of California, caves, and ancient Indian occupying a rock shelter, broken down outboard motor yacht DQPvADQ in La Paz and cruised about half way making a preliminary survey of the many islands, villages, including one in which the natives were with the only evidence of ^'civilization” being a , a rusty 22 rifle and a singer sewing machine! Flying from Tia Juana to La. Paz on the Trans Mar de Cortez Airline, the director was able to observe wave-cut terraces representing high sea levels comparable to those on the California Channel Islands, Sr. Mayo Obregon President, and Gueillermo Escudero Lujan, Sales Manager of the Airlines, were most helpful in providing information about caves in Baja, California* The DOPADO Santa Cruz trip: On the invitation of Mr. and Mrs. F. W. Conant, another effort was made to enter Painted Cave on Sa.nta Cruz Island. This giant sea cave is acces­sible only in small boats and favorable weather. The director has been able to enter pa.rt way twice in 22 years and many attempts to measure and photo­graph the cave have failed, cue to unfavorable weather. Publications: During the early part of 1960, WSX Contributions No. 15 and 16 were pub­lished. No. 15, by Phil C. Orr, Late Marine Terraces on Santa Rosa Island, California, in the Bulletin of the Geological Society of America, Vol. 71, pp. 1113-1120. In this, their wave-cut platforms with their marine and ter­restrial fossil-bearing covers are named (Santa Rosa Island Formation-Gara-non, Fox and Tecolote members), and are shown to be of late Pleistocene age by means of radiocarbon dates. Ho. 16, by Wallace S. Broecker and; Bdwin A. Clson of Lamont Geological Observatory, and Phil C*. Orr, Radiocarbon Measurements and Annual Rings in Ca.ve Formations, Nature, Vol. 185, Ho. 4706, pp. 93-94. This is a technical report on a number of radiocarbon measurements made upon a speleothem con­taining human bone from Moaning Cave in California. It is notable as the first successful radiocarbon measurement of speleothems. In the fall of 1959, the WSX in OBSERVATIONS No. 6, published Abstracts papers given at the 6th Great Basin Archeological Conference. Authors and titles of papers included are: of Joseph IT.* Birman C* W. Ferguson George Kennedy Bruno B. Sables Glacial Advances in the Central Sierra Nevada* Big Sagebrush and other Woody Desert Plants as Pos­sible Tools in Archeological Dating. The Application of Thermoluminescence in Dating Ar­cheological Objects. Paleoclimatical Studies of Cave Strata by Emission Spectography.
