Infrared Sensors Detect Desert Ruins in New Mexico

Monday, April 07, 2014

(Cynthia Hotujec-Kantner)JACKSONVILLE, FLORIDA—A small, remote-controlled drone carrying a heat-sensing camera has helped archaeologists to get a sense of the Blue J community—an eleventh-century, ancient Puebloan settlement of nearly 60 households situated around open plazas in New Mexico’s desert. The settlement is just south of Chaco Canyon, but archaeologists had not found a monumental great house, nor a great kiva, that are typical of Chaco architecture. The heat-sensing camera, however, detected the sun-warmed masonry of a large, circular structure that may be a ceremonial kiva hidden beneath the earth. “The drone work was able to show us that at least some of the sites are much larger below the surface than can be seen on the surface,” archaeologist John Kantner of the University of North Florida told Western Digs. He had thought that the people who lived at Blue J may have resisted the influence of Chaco Canyon. “If it is indeed a great kiva, I’ll have to change my interpretation of how villages like Blue J interacted with Chaco Canyon,” he added.
