IN REPLY REFER TO: UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY ACgays WASHINGTON 25, D.C. NOV 4 7960 Brig. Gen. A. D. Starbird, Director Division of Military Application U. S, Atomic Energy Commission Washington 25, D. C. Dear General Starbird: In 1951 and 1952, the Geological Survey cooperated with the Office of Naval Research in carrying out a deep-drilling project on Eniwetok Atoll. The work was supported by the Armed Forces Special Weapons Projéet and the Atomic Energy Commission. ‘Two of the deep holes succeeded in reaching the basaltic foundation of the atoll at depths in excess of 4,000 feet. The foundation rock was sampled as were the sediments drilled at higher levels. A final report describing the deep holes, and the materials obtained in a large series of shallow holes on islands and on the reef, has now been completed. Two copies of this report are enclosed. The Geological Survey will furnish any additional copies that may be desired. Sincerely yours, Charles A. Anderson Chief Geologist Enclosures 2 ley ate Tee oferhez — ENCESURS CONFIPMED TO!
