Christopher O’Brien investigated over one thousand paranormal events reported in the San Luis Valley—located in south-central Colorado/north-central New Mexico. Working with law enforcement officials, ex-military, ranchers and an extensive network of skywatchers, he documented what may have been the most intense wave of unexplained activity ever seen in a single region of North America. His ten-year investigation resulted in the three books of his “mysterious valley” trilogy: The Mysterious Valley, Enter the Valley, and Secrets of the Mysterious Valley.
His meticulous field investigation of UFO reports, unexplained livestock deaths, haunted sites, Native American legends, cryptozoology, secret military activity and the folklore, found in the world’s largest alpine valley, has produced one of the largest databases of unusual occurrences gathered from a single geographic region. He is currently working with a team of specialists installing a high-tech video surveillance and hard-data monitoring system in and around the San Luis Valley. His latest book, Stalking the Herd, is being called the most important book ever written examining our relationship with cattle and how this has manifested into the modern “cattle mutilation” mystery.
