Constanza Ceruti
Adventurer, Archaeologist

A National Geographic Emerging Explorer, high-altitude archaeologist Constanza Ceruti specializes in excavating Inca Empire ceremonial centers on the summits of sacred Andean mountains. Constanza's most impressive find to date took place on a 22,100-foot summit, where the expedition she co-led unearthed the three best-preserved mummies ever discovered. "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.
