LOS ANGELES, CA (Catholic Online) - The village, called Blue J is a 1,000-year-old village first identified by archaeologists in the Seventies. Located at about 43 miles south of the famed Chaco Canyon site in northwestern New Mexico. Blue J contains nearly 60 ancestral pueblo-styled centered about what was once a large spring.

The ruins of Blue J are currently covered up by vegetation and buried in eroded sandstone blown in from nearby cliffs. The ancient structures have been only partially studied through excavations. A team of archaeologists flew a small camera-equipped drone over the site last June to find out what infrared images might reveal under the surface.

"I was really pleased with the results," Jesse Casana, an archaeologist from the University of Arkansas says. "This work illustrates the very important role that UAVs (unmanned aerial vehicles) have for scientific research."

Co-author John Kantner of the University of North Florida had previously excavated at the site. Drone images showed stone compounds Kantner had already identified and ones that he didn't know about.

Thermal images revealed a dark circle just inside the wall of a plaza area, which could represent wetter, cooler soil filling a kiva, or a huge, underground structure circular that would have been used for public gatherings and ceremonies.

Locating the kiva at Blue J would be a significant find. Blue J has been considered unusual among its neighbors because it lacks the monumental great houses and subterranean kivas that are the hallmark of Chaco-era Pueblo sites.

The images also could guide archaeologists' trowels before excavating.

"Now that we know what household compounds look like in thermal imaging, we could use it to prospect for structures at other sites," Casana says.
