A National Geographic Emerging Explorer, high-altitude archaeologist Constanza Ceruti specializes in excavating Inca Empire ceremonial centers on the summits of sacred Andean mountains.

"When we found the mummies, I remember a profound silence falling over the group. It is so humbling to look into the eyes of another human being from half a millennium ago." A professor at Catholic University in Salta, Argentina, Constanza looks forward to sharing the wonders of Patagonia with National Geographic travelers.
