ALBUQUERQUE, N.M. (AP) — Recently published research describes how archaeologists outfitted a customized drone with a heat-sensing camera to unearth what they believe are ceremonial pits and other features at the site of an ancient village in New Mexico.

The discovery of the structures hidden beneath layers of sediment and sagebrush is being hailed as an important step that could help archaeologists shed light on mysteries long buried by eroding desert landscapes from the American Southwest to the Middle East. The results of the research were published earlier this month in the Journal of Archaeological Science.
