Report issued by the U.S. Bureau of Mines discussing the mining practices and expenses of the United Verde open-pit mine west of Jerome, Arizona. As stated in the introduction, "the purpose of this paper is to present the methods used in developing and operating the mine, and to discuss the problems encountered" (p. 1). This report includes tables, maps, and illustrations.

Report describing the results of a program to test and evaluate the cross-country mobility of the Overland Train (a logistical cargo carrier) in a desert environment. This study used a system for terrain classification developed by the U.S Engineer Waterways Experiment Station as part of the tests made on various courses at the U.S. Army Yuma Proving Ground in Arizona.

From introduction: The Monument No. 2 mine is in the Navajo Indian Reservation, Apache County, Arizona, about 20 miles southwest from the San Juan River at Mexican Hat, Utah, and 26 miles southwest from Mexican Water, Arizona. The property has been operated, since its discovery, by Vanadium Corporation of America, which holds a 10-year mining lease, granted through the Interior Department, to 43 acres of ground. History of the discovery of the deposit is vague, but reportedly it was first seen around 1942 by a Navajo who mentioned the occurrence to Harry Goulding, Indian trader, who in turn advised D. W. Viles of Vanadium Corporation of America. Minor portions of the deposit are held by Cato Sells and Harvey Black, Navajos, under mining permits issued by the Navajo Tribal Council. The Sells acreage is being operated by Climax Uranium Corporation.

Purpose: A reconnaissance was conducted during parts of August and September, 1956, of an area about two miles square in the southern Carrizo Mountains where the Permian Cutler formation, including its DeChelly member, and the Triassic Shinarump member of the Chinle formation, are exposed. The purpose was to appraise the uranium potential of the area and to determine the cause of bleaching in the DeChelly. Extensive uranium mineralization in the Salt Wash member of the Morrison formation around the Carrizo Mountaind suggested that the Shinarump, a good producer in other areas on the Colorado Plateau, might be mineralized here as well. Bleaching, as shown in the DeChelly; has proven such a useful guide to uranium at other localities as to merit investigation here.

From introduction: The purpose of an airborne radioactivity survey is to locate ground areas of higher than normal radioactivity which might lead to discovery of uranium mineralization. For this type of survey, gamma-ray detection equipment employing either a geiger counter or a scintillation counter can be mounted in a fixed wing aircraft or a helicopter.

From introduction: A program of uranium investigations and geologic mapping on the Navajo Indian Reservation in Apache and Navajo Counties, northeastern Arizona (fig. 1) was undertaken by the U. S. Geological Survey on behalf of the Atomic Energy Commission during the field seasons of 1951 and 1952. Field work on this program has been completed and preliminary copies of the maps, which cover an area of about 700 square miles, are inclosed as part of this report. The two principal objectives of the program were to establish geologic criteria useful as guides in prospecting for uranium deposits, and to appraise the favorableness of the Shinarump conglomerate and other Triassic rocks for the occurrence of uranium deposits in order to select areas that deserve exploration for concealed deposits.

A reconnaissance of many of the copper deposits in the Red Beds of New Mexico, Arizona, Oklahoma, and Texas that was carried out in the summer of 1951 yielded chiefly negative results from the standpoint of uranium production. With the possible exception of the Grand View mine, which will require further investigation, none of the deposits seen in this survey gives promise of being of commercial interest for uranium at the present time.

The tabulations on these pages include all of the known areas in Colorado, Utah, New Mexico, and Arizona having economically important uranium-vanadium deposits of the type which are generally referred to by the terms roscoe-lite and/or carnotite. Though similar deposits are known to exist in other areas they are to be viewed as being little more than mineralogical curiosities.

Report summarizing information regarding the mineralogy of uranium ores of the Colorado Plateau. The report includes sections on classification, mineralogy of the primary unoxidized ores, oxidation sequence and mineralogy of vanadiferous uranium ores, mineralogy of oxidized nonvanadiferous uranium ores, relation of oxidation to water saturation of ore, relative stability and size of oxidized deposits, secondary enrichment, and time and depth of oxidation.
