About this image
The Bandelier tuff dominates the landscape in much of the Jemez Mountains, particularly in the vicinity of Los Alamos, NM. There were two massive ignimbrite eruptions, the first was 1.6 million years ago and the second was 1.2 million years ago. These eruptions formed the lower and upper Bandelier tuff respectively.
