From introduction: An autunite deposit in the SW 1/4 sec. 25, T. 10 N., R. 13 W. San Bernardino meridian, was visited by F. M. Chace on May 6 and 15, 1950. The deposit is about 100 yards west of a north-south country road and is at an altitude of approximately 2,775 feet. The autunite-bearing tuffaceous sandstone strikes N. 35-40 W. and dips 20 -25 SW. It has been traced about 40 feet along the strike at the base of the outcrop and for about 20 feet up the dip. Insufficient work was done to give an accurate idea of the size of the deposit or to determine if other autunite-bearing beds are present.

Abstract: Uranium associated with peat humus was discovered in a boggy meadow in the Sierra Nevada of Kern County, California, in the fall of 1955.

This is a report on the Sunset-Midway oil field in Kern County, California, including the geology and production of oil.

From abstract: Airborne radioactivity surveys in the Mojave Desert region, Kern, Riverside, and San Bernardino counties were made in five areas recommended as favorable for the occurrence of radioactive raw materials: (1) Rock Corral area, San Bernardino County. (2) Searles Station area, Kern County. (3) Soledad area, Kern County, (4) White Tank area, Riverside and San Bernardino counties. (5) Harvard Hills area, San Bernardino County. Anomalous radiation was detected in all but the Harvard Hills area.

Abstract: An area of high anomalous radioactivity and visible uranium minerals is associated with a nearly vertical north 70° west trending shear zone.

Abstract: Approximately 10 square miles of mainly igneous rocks of the western Mojave Desert were covered by this airborne radiometric survey in 173 hours of flying time.

From purpose and scope: The purpose of this project was to determine the uranium favorability of Mesozoic intrusive rocks and Tertiary volcanic and sedimentary rocks in the central Mojave Desert. The project was conducted by Bendix Field Engineering Corporation (BFEC) under the auspices of the Grand Junction Office of the U.S. Energy Research and Development Administration (ERDA). The scope of the project included determination of the uranium content of different rock types, determination of the nature and extent of rock characteristics favorable for the formation of uranium deposits, and examination of known uranium deposits.

Abstract: "Tests were conducted on a 1:50-scale model of Isabella Dam Spillway to determine the adequacy of proposed spillway, dam, and channel improvements. The model reproduced an area of the reservoir 800 ft wide by 1,100 ft long, the spillway, and the entire length of the exit channel. Unsatisfactory flow conditions were observed in the vicinity of the spillway crest due to approach conditions to the spillway. Large cross waves, present in the exit channel just downstream of the spillway, resulted in occasional overtopping of the right wall. A grouted rock dike that provided satisfactory flow conditions at the spillway and downstream throughout the exit channel was placed adjacent to the existing spillway approach wall."

From introduction: The purpose of this report is to describe the geology of the Elk Hills and the occurrence of the oil and gas, to trace the movements of oil, gas, and water in the developed areas, and to discuss the oil possibilities of the undeveloped parts. The history of the field and its production also are set forth.

Report regarding an airborne gamma-radioactivity survey that took place in the 2,800 square mile area around the Los Angeles region in California. Topics include the types of bedrock noted in the area as well as their levels of radioactivity.

"An Aerial Radiographic Measuring Survey (ARMS) of the Arguello area was made for the Civil Effects Test Operations, Division of Biology and Medicine, U.S. Atomic Energy Commission, by Edgerton, Germeshausen & Grier, Inc.(EG&G), between Apr. 5 and Apr. 29, 1962. The survey was part of a nationwide program to measure the present environmental levels of gamma radiation" (p. 5).
