Seirer_180428_8503194.jpgA Face of Cavities Air pockets in compacted volcanic ash, called tuff, left countless cavities in the towering cliffs of Bandelier National Monument near Los Alamos, New Mexico. Those cavities, many of them small but easily enlarged with hand tools, are believed to have provided housing for ancient populations as many as 11,000 years ago.
