Located in the large desert area adjacent to Death Valley, it is currently used as a nuclear waste repository designated by the United States Department of Energy. The mountain lies in the mountainous Great Basin with numerous valleys and ridges. The Yucca Mountain has a very rich geological history that dates back hundreds of millions of years ago. Yucca’s base layer of rocks were first deposited during the Pre-Cambrian geological period billions of years ago. This was followed by other layers of rocks that were deposited throughout the years including carbonate, shale, and other marine sedimentary rocks. Because of its placement amongst faults, many volcanic and seismic activity has occurred. These volcanic eruptions have built up layers of ignimbrite (See Pic 1 below) which consists of welded and non-welded tuff. These alternating layers of welded tuff and non-welded tuff have many geological implications that are of interest to geological researchers. This tuff is densely made up of volcanic ash and rock fragments from the lava which were fused together to form many layers. The volcanic remains and layers have come together to form the ridge line that we see today as the Yucca Mountain. It is very clear to see that the geographical and geological properties of the Yucca Mountain makes it an interesting…
