Earthquake Resistance of Earth and Rock-Fill Dams, Report 2: Analysis of Response of Rifle Gap Dam to Project Rulison Underground Nuclear Detonation

Description: Summary: The motion of Rifle Gap Dam was measured in September 1969 during the Project RULISON underground nuclear explosion. The observed response was then compared with the response computed in a mathematical model. Observed and computed responses were similar. From this study it appears that the mathematical models used are applicable to the design and analysis of soil structures, at least for ground motion intensities comparable to those observed at Rifle Gap Dam.

Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples

Description: From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."

Ground-Water Potential of the Leadville Limestone on the White River Uplift in Garfield and Rio Blanco Counties, Colorado

Description: Purpose and scope: This report describes a preliminary reconnaissance of the water-bearing properties of the Mississippian Leadville Limestone in the western part of the White River Uplift (synonymous with the White River Plateau). The purpose of this preliminary investigation is to determine areas of the Leadville Limestone suitable for exploratory drilling and testing at relatively shallow depths to confirm the quality of water in storage.
