Chemical composition of ground water and the locations of permeable zones in the Yucca Mountain area, Nevada

Ten wells in the Yucca Mountain area of southern Nevada have been sampled for chemical analysis. Samples were obtained during pumping of water from the entire well bore (composite sample) and in one instance by pumping water from a single isolated interval in well UE-25b number 1. Sodium is the most abundant cation and bicarbonate the most...

Uranium transport in the Walker River Basin, California and Nevada

During the summer of 1976 waters from tributaries, rivers, springs and wells were sampled in the Walker River Basin. Snow and sediments from selected sites were also sampled. All samples were analyzed for uranium and other elements. The resulting data provide an understanding of the transport of uranium within a closed hydrologic basin as well as...

Cold War Craters

The most cratered landscape on Earth is a Nevada desert called Yucca Flat. The craters are the remnants of decades of nuclear tests conducted by the United States since early in the Cold War.

Historical images from the USGS EROS archive show the changing cratered landscape. A 1952 aerial photo shows that such testing had already begun. A declassified satellite image
