Collection of reports on Death Valley, the bordering region of California, Nevada, Arizona, and Utah. Reports include birds, reptiles and Batrachians, fishes, insects, mollusks, trees and shrubs, cactuses and yuccas, and list of localities in the reports.

From abstract: The purpose of this preliminary electrical resistivity investigation of Holiday Mesa, Monument Valley region, San Juan County, Utah, was to determine the feasibility of a detailed survey to delineate channels cut into the Moenkopi formation and filled with sediments of Shinarump conglomerate. These structures are in many places related to the localization of uranium ore.

"This report presents engineering details, statistics, and individual borehole histories of the 27 holes drilled for this project." (from Introduction)

Illustrations, including maps, accompanying a report detailing a ground check of faults and joints in the San Rafael Swell in Emery County, Utah. Fault and joint trends, direction of fault displacements, and some instances the amount of displacement, were mapped.

Discussing major joint trends in the Circle Cliffs area, in Garfield County, Utah.

Discussing a ground check of faults and joints made in the San Rafel Swell in Emery County, Utah.

An interim report regarding the exploration of the Yellow Cat Area, Grand County, Utah.

From to the files: To date, all the mineralization seen in the Monument Valley area in the Shinarump formation has been in scour channels. The mineralized rock occurs at or near the bottom of the channel. On Hoskinnini Mesa, all the channels examined to date contain some mineralized material. Channels observed may in some cases contain copper without apparent uranium mineralization; others definitely exhibit copper-uranium mineralization.

Introduction: It is the purpose of this guide to describe the general geological features of the Marysvale area which may aid in exploration for uranium.

Report issued by the U.S. Bureau of Mines discussing water-control issues at the Chief Mine in Juab County, Utah. Unique methods for water control are presented. This report includes tables, maps, illustrations, and photographs.

From Purpose and Scope: "The Marble Canyon Quadrangle (2º), an area of 20,634 km2, is in northeastern Arizona (Fig. 1). The quadrangle was evaluated to a depth of 1500 m to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Favorable environments, as determined by surface and subsurface investigation, are those that could contain uranium deposits of at least 100 tons U3O8 in rocks with an average grade not less than 100 ppm U3O8. Work on the Marble Canyon Quadrangle began March 6, 1979, and ended February 29, 1980."

Appendices containing survey data of the Marble Canyon Quadrangle in northeast Arizona for uranium availability to accompany a report on national uranium resources in Arizona and Utah.
