Technical Report ·
DOI:https://doi.org/10.2172/6441344· OSTI ID:6441344

Exploratory hole UE7nS was drilled to a depth of 672.1 m in East-Central Yucca Flat, Nevada Test Site, as part of a program sponsored by the Nuclear Monitoring Office (NMO) of the Advanced Research Projects Agency (ARPA). The purpose of the program is to determine the geologic and geophysical characteristics of selected locations that have demonstrated anomalous seismic signals. The purpose for drilling UE7nS was to provide the aforementioned data for emplacement site U7n. This report presents lithologic and stratigraphic descriptions, geophysical logs, physical properties, and water table measurements. An analysis of these data has been made and a set of recommended values is presented.
