The formation that makes up Yucca Mountain was created by several large eruptions from a caldera volcano and is composed of alternating layers of ignimbrite (welded tuff), non-welded tuff, and semi-welded tuff. The tuff surrounding the burial sites is expected to protect human health as it provides a natural barrier to the radiation. It lies along the transition between the Mojave and the Great Basin Deserts.
