J. E. Kibler D. C. Muller 1983 Drill hole USW G-1 was drilled at Yucca Mountain, Nevada Test Site, Nevada, as part of the ongoing exploration program for the Nevada Nuclear Waste Storage Investigations. Contract geophysical well logs run at USW G-1 show only limited stratigraphic correlations, but correlate reasonably well with the welding of the ash-flow and ash-fall tuffs. Rocks in the upper part of the section have highly variable physical properties, but are more uniform and predictably lower in the section. application/pdf 10.3133/ofr83321 en U.S. Geological Survey, Commercial geophysical well logs from the USW G-1 drill hole, Nevada Test Site, Nevada reports
