The following report presents the lithologic log of the description of the tuff penetrated by the U12g.06-U1 core drill hole located at the end of the U12g main tunnel at the Area 12, Nevada Test Site.

From Introduction: "As a result of research accomplished during Operation BREN in 1962, it has been proposed that a monoenergetic point neutron source be constructed and operated on the same tower. The field experiment which would be conducted at this time has been designated as Operation HENRE (High Energy Neutron Reactions Experiment)."

The following report provides a geological map of sections of the Thirsty Canyon South East quadrangle of Nye County, Nevada.

Preliminary 16 x 7.5 minute map of the Thirsty Canyon quadrangle, showing geology, roads, drainage, meridians and parallels, triangulation stations, and air-photo centers and wing points.

Report on an evaluation of the Sand Springs Range as a possible location for an underground nuclear study (Shoal Event). Various tests to determine the site's suitability included aerial photography and mapping of the area through various means; drilling and bulldozing to conduct mineralogical and other physical evaluations; gravity, aeromagnetic, and refraction surveys; and studies related to the hydrology of the location and surrounding areas.

Plates documenting results of some tests performed during the site evaluation of the Sand Springs Range including aerial photography, various types of mapping and surveying of the physical and hydrological aspects of the location, and other supplementary materials.

The following documents are aseries of plates to accompany the final report of "Geological, Geophysical, Chemical, and Hydrological Investigations of the Sand Springs Range, Fairview Valley, and Fourmile Flat, Churchill County, Nevada".

From abstract: Project Dugout was a chemical explosive row charge cratering experiment in hard rock conducted at the AEC Nevada Test Site as part of the Plowshare Program for development of nuclear excavation technology.

From abstract: A comprehensive geologic and engineering investigation was undertaken at the site on Buckboard Mesa selected for the SULKY event, a nuclear cratering experiment, conducted in dry basalt.

Introduction: This report describes the occurrence, movement, and discharge of perched ground water in tuffaceous rocks that cap and underlie Rainier Mesa -- the site of the first series of underground nuclear detonations made by the Atomic Energy Commission at the Nevada Test Site.

From abstract: Close-in air blast measurements were made on the Dugout shot. Major constituents of the blast wave were the ground-shock-induced pulse and the pulse from venting gases. The ground-shock-induced pulse was the dominant one at all stations.

From introduction: "This report was compiled to bring together the well data collected by the U.S. Geological Survey since 1960. This compilation includes data on 63 wells and test holes which were drilled since the Moore reports were prepared, or which were deepened or otherwise modified since 1960."
