The Alliance Studying Paranormal Experiences, based in the small village of Angel Fire, claims the region has received multiple visits, the Sangre de Cristo Chronicle reports. Alliance President Janet Sailor calls the area a "UFO hot spot."

She reported the find to Sailor, and last weekend, Dee Gragg, a New Mexico State University professor and assistant director of the state chapter of the Mutual UFO Network, came to Angel Fire to discuss the circles. Gragg said the important question is what kind of craft landed in the valley. He regards the question of whether there was a landing as answered. At a meeting Saturday, he showed slides of the circles. Gragg described them as most likely the footprints of several small ships, either unmanned probes or carriers of small aliens.
