From abstract: A reconnaissance radioactivity survey of the Anaconda Copper Mining Company open-pit copper mine at Yerington, Nevada, was made in October 1953 to investigate the reported occurrence on one of the mine dumps of rock containing 0.022 percent uranium.

This report discusses upland erosion control, revegetation activities, and long-term maintenance plans for the Ruby Pipeline Project, a pipeline that extends from Wyoming to Oregon.

The purpose of this study is to investigate anisotropy of mechanical properties, namely, compressive strength and modulus, for Tiva Canyon welded tuff from the starter tunnel at Yucca Mountain. Mechanical properties of Tiva Canyon Tuff are needed for the design of the ramps and drifts within the Tiva Canyon horizon. Approximately one cubic foot block samples, all of which were from the thermo -- mechanical unit TCw, were obtained from a muck pile containing excavated rock from the starter tunnel. Specimens were cored from the block samples in two distinct orientations: parallel and perpendicular to the lithophysal cavity orientation. Since lithophysal cavity orientation is predominantly horizontal in the field, parallel specimens can be considered horizontal and perpendicular specimens vertical with respect to the rock mass. The specimens were NX sized (5.4 cm diameter) and had a length-to-diameter ratio of 2:1. The air dried specimens were tested at room temperature in a triaxial chamber at confining pressures of 0.1, 5, and 10 MPa, and at a compressive axial strain rate of 10{sup {minus}5} s{sup {minus}}. The Young`s Modulus values were calculated by a least squares fit of stress - strain data between 10 and 50% of the ultimate strength.

From abstract: Many residents of the Nevada area carried film badge radiation dosimeters during Operation Plumbbob in 1957. Badge readings in specific localities appear to follow the logarithmic-normal distribution.

From introduction: This report details the results of instrument recordings of a nuclear explosion where ground zero was near the top of Rainier Mesa.

The following report provides a geologic map of the Thirsty Canyon quadrangle in Nye county, Nevada.

The following report follows geological investigations made on the 410 Area of the Nevada Test Site.

Report discussing deposits of uranium in beds of carbonaceous shale and lignite in the Goose Creek district. The highest concentrations of uranium were found in the central part of the Salt Lake formation.

The following report covers the study of a small composite stock at Oak Spring, Nevada, known as Climax granite to study the seismic effect of a deep nuclear explosion contained in a large volume of unfractured rock.

Report discussing the search for uraniferous coal in areas of California, Oregon, and Nevada. The reconnaissance and its results are described in sections divided by regions searched.

Appendices containing data on uranium availability in the McDermitt Quadrangle to accompany a report on U.S. uranium resources in Nevada.

From Purpose and Scope of Study: "The McDermitt NTMS Quadrangle, Nevada, was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. Geologic environments were evaluated primarily on the basis of surface investigations; only a limited amount of subsurface data was available. Each environment was categorized as favorable, unfavorable, or unevaluated for uranium deposits."

The following report describes the computer technique for tracing seismic rays in two-dimensional geological models in the state during the time this report was written, and presents some preliminary results.
