Skinwalker Ranch is a 512-acre property tucked away in the northeast corner of Utah that, apparently, UFOs—and the men studying them—just can't get enough of.

In the 1960s and 70s, there was a flurry of UFO sightings in the Uintah Basin. Then, in the mid 90s, stories about Skinwalker and strange goings-on at the ranch started to emerge. The stories range from cattle mutilations to UFOs.
