6. San Luis Valley
Colorado’s San Luis Valley is certainly one of the few mysterious places in the #world which can boast its own UFO watch tower.
Built by Judy Messoline in response to thousands of UFO sightings and hundreds of unexplained animal mutilations, the tower allows skeptics to scan the night skies for strange flying phenomenon.
For the locals, however, it’s the surgically precise animal mutilations that keep them up at night, with rumors of aliens and “Phantom Surgeons of the Plains” floating around the region.
