Abstract: The Valley of Fire-Muddy Mountains region, located 20 to 30 miles northeast of Las Vegas, Nevada, was given approximately 25-percent airborne radioactive coverage during the fall of 1954. Rocks in the area range from Cambrian to Miocene in age. Uranium was known to occur at two sedimentary horizons at the time the airborne program began. One new uranium-bearing sedimentary horizon was discovered by the airborne reconnaissance. Of 15 anomolies detected, only 11 were posted as the remainder were claimed at the time of the survey.

From introduction: Under the general supervision of the Health Division of the Los Alamos Scientific Laboratory, the U.S. Geological Survey is participating in geologic and hydrologic studies of the tile field constructed in Jackass Flats in the southwestern part of the Nevada Test Site as related to waste disposal, M. D. Shutler rendered valuable assistance in obtaining and evaluating portions of the data in this report. These investigations were done on behalf of the U.S. Atomic Energy Commission and were supported by the Division of Reactor Development and by the Albuquerque Operations Office.

"The surficial deposits of Yucca Flat, divided into eleven units, are shown at a scale of 1:48,000 (fig. 1A). Major rock types of the bordering bedrock areas are indicated, as are the lithologies of portions of the surficial units. The map explanation (fig. 1B) includes a description of the surficial units."

From Introduction: "The Kingman Quadrangle, Arizona, Nevada, and California (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits.

Appendices containing uranium occurrence data in the Kingman Quadrangle, in addition to chemical analyses data to accompany a report on U.S. uranium resources in Arizona, Nevada, and California.

From introduction: The maps and tables comprising this report are being transmitted at this time to provide interested users with a summary of the geology of the Ul2e tunnel system. The system was constructed to provide access to underground test sites. This report contains part of the geologic information obtained from investigations conducted by the U. S. Geological Survey to determine the geologic environment of the underground test sites. Results of geophysical and radiometric surveys, and physical properties are being studied. This work was done on behalf of the U. S. Atomic Energy Commission.

"The purpose of this profile is to summarize the ecological information available for and relevant to stream and riparian habitats of the Great Basin. The Great Basin comprises the northern half of the Basin and Range physiographic province and covers most of Nevada and western Utah and portions of California, Oregon, and Idaho. The entire basin actually consists of numerous subbasins and mountain ranges which present an extremely diverse physical setting" (p. iii).
