The following report describes the high pressure and temperature homogeneous reactor experiment which has been started at Los Alamos, as well as the hazards and safety aspects for the experiments.

Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Permian and Pennsylvanian age south of Coyote, Mora County, New Mexico. Detailed mapping and sampling of these deposits indicate that they occur in carbonaceous zones in shales and arkosic sand-stones. Samples contain as much as 0.067 percent uranium. A yellow radioactive mineral found in the deposits was identified as metatyuyamunite. All of the samples were collected near the surface and are weathered. It is recommended that physical exploration be undertaken to determine the extent and grade of uranium-bearing zones at depth.

From introduction: The reconnaissance was made during the summer of 1951 by two field parties: (1) a reconnaissance in parts of Oklahoma, Texas, New Mexico, and Arizona by Russell Gibson, and (2) Geological Survey reconnaissance in parts of New Mexico,.Colorado, Utah, Idaho, and Wyoming (by the writers), the results of which are summarized in this report.

Letter from Claude S. Fernandez, LULAC District Governor of Carlsbad, New Mexico, to John J. Herrera, dated December 29, 1952. The letter provides the location of the LULAC Supreme Council meeting to be held at the Crawford Hotel in Carlsbad, New Mexico, on January 17 and 18, 1953.

Objectives: The purpose of this project was to study in detail the factors controlling the formation of fractures and the fracture pattern actually developed in an area transitional between Colorado Plateau and Basin and Range type structures.

From abstract: The copper and uranium-vanadium deposits of the Coyote district, Mora County, N. Mex., are confined to the lower 2,000 feet of the Sangre de Cristo formation of Pennsylvanian and Permian age. A narrow belt of deposits in steeply dipping or overturned rocks extends for 7 miles along Coyote Creek south of Guadalupita. Earlier studies showed that the copper deposits contained uranium, but both the reserves and the uranium content of the copper-bearing shale are too low to permit the recovery of uranium. However, small, commercial grade uranium deposits have been discovered in sandstone.

This is a geological map of the uranium region of the Colorado Plateau.

A report about copper and uranium deposits of the Coyote district, Mora County, N. Mex., are confined to the lower 2,000 feet of the Sangre de Cristo formation of Pennsylvanian and Permian age.

Report discussing the investigation of possibly commercial amounts of thorium, niobium and rare earths which were found in veins of igneous rock areas in Laughlin Peak, New Mexico.

The following report is a synopsis of readily available information on the mineralogy, thickness and areal extent of soluble salt deposits in the Ochoa series of Permian age in southeastern New Mexico and western Texas. It's part of a more extensive investigation of salt being carried out by the U.S. Geological Survey in connection with its Investigation of Geologic Processes project on behalf of the Division of Research, U.S. Atomic Energy Commission.

Letter from Dr. Valin Woodward to the president of the Tarrant County Medical Society asking that they file information about his brother (Mortimer) who has just died and was also a member of the group. He outlines a brief biography of his brother's life, particularly in relation to his health after having a kidney removed in 1926 and then moving to New Mexico due to tuberculosis.

A report summarizing geologic investigations (as well as recommendations for drilling) in the Coyote District, Mora County, New Mexico.

A letter written to Mr. Carswell, from R. D. Hill, Casa Grande Lodge, Albuquerque, New Mexico, dated December 20, 1950. Hill monologues on politics and his concern for the possible loss of their fundamental freedoms and of their way of life, yet, optomistically advising of new business with the government confirming that KNUBLEN coffee is now being used at several of the governmental set-ups. He outlines his business travel itinerary and requests information regarding the large lathe advising that he may desire to have some machine work done by Dalton.

Letter from I. H. Kempner to Mr. W. W. Overton, Jr., discussing their recent trip to Santa Fe, where they stopped in a couple cities before then. He expresses his thankfulness to him and Evelyn for making their trip memorable.
