Episode 181 - The region in the South Nahanni River played host to several unexplained and disturbing occurrences in the first half of the twentieth century. Between1905 and 1945, in the remote and rugged wilderness in the lower west corner of Mackenzie Mountains in the Northwest Territories and other unexplained events, there were at least 44 people who went missing under mysterious circumstances.

Most unsettling of all were the four bodies that were found during that time in three separate incidents. All of the corpses had been decapitated, and their heads were never recovered, earning the area the ominous nickname, the Valley of the Headless Men. No one knows who was responsible for these horrific mutilations or what became of the other missing people.
