Nahanni National Park or Nahanni Valley is also known as the Deadmen Valley, Headless Valley, or the Valley of the Headless Men due to the strange disappearance of a number of gold prospectors whose bodies were later discovered headless.
After the decapitated bodies of the McLeod brothers were discovered in 1908, stories of the haunted valley and the missing treasure emerged, despite the absence of considerable gold.

This enigmatic valley of the South Nahanni River, located in the southernmost portion of Canada’s Mackenzie Mountains, was one of the first four natural heritage sites inscribed by UNESCO as a World Heritage Site in 1978 because of its stunning wild rivers, gorges, and waterfalls.
It is assumed that the area was first inhabited between 9,000 and 10,000 years ago. Yohin Lake and a few other locations inside the park have shown evidence of prehistoric human activity.
Numerous tribes feared settling in the area because they believed it was inhabited by bad spirits, specters, and demons.
Others claimed a race of terrifying, hairy giants that inhabited caverns dug into the canyon walls. These primitive mountain people, led by a gorgeous, pale-skinned chieftain, slaughtered and ate everyone who invaded their area.
Those who did visit, such as the native Dene Indians, felt that the valley was a cursed location permeated by terrible medicine – a malevolent, supernatural spirit that hovered over the area like the valley’s constant fog. They spoke of strange beasts lurking in the wide woodlands and were plagued by the secretive, hostile, and murderous Naha mountain tribe.
This Naha tribe was rumored to comprise of ferocious warriors who donned masks and armor ornamented with terrifying iconography and were notorious for ruthlessly beheading their victims. It was rumored that warriors of the Naha tribe were larger than average and wielded odd and potent weapons that had never been seen before.

The deadly Naha tribe has become one of the region’s numerous mysteries, as the entire tribe is supposed to have abruptly and unexpectedly vanished from the face of the planet, and what happened to them has never been determined. They appear to have vanished without a trace.
In 1905, Frank and Willie McLeod set out for the Nahanni Valley in pursuit of The Lost Gold Mine, a fabled lost mine rumored to exist somewhere inside the park. However, they never returned.
A number of years later, in 1908, the bodies of the McLeod brothers were discovered on the Nahanni River’s banks. However, their heads were nowhere to be located. The two men were slain and left for the next group of explorers to discover on the riverbank. In a huge valley, they discovered two skeletons near their camp at the river’s bank. One man slept with his arm extended towards his rifle, while his brother’s blankets were flung across him as if he had jumped out of bed.
In 1917, Martin Jorgenson began his search for gold in the Nahanni Valley. Soon after Jorgenson sent out letters claiming to have discovered gold, his cabin was inexplicably destroyed by fire. His skeletal remains were discovered among the ashes. Similar to the McLeod brothers, Jorgenson’s body was discovered headless.
In the winter of 1922, John O’Brien’s body was discovered on a mountainside near the Headless Valley, slumped over a mound of tinder with a matchbook in his hand, as if he had frozen to death while attempting to start a fire.

Ernest Savard, an Ontario miner, perished in the same manner in 1945. His headless body was discovered in his sleeping bag.
Other men who entered the valley, such as trappers Bill Epler and Joe Mulholland, mysteriously vanished.
During the same period in the park’s history, a series of mysterious plane disasters gave the Funeral Range, which borders the scary Hell’s Gate rapids, its name.
UFO sightings and other weird lights were also reported in the park, and to this day, cryptid-obsessed bloggers relate tales of Amphicyonidae—a bear-dog hybrid that became extinct during the Pliocene—prowling the valley, as well as Bigfoot activity in restricted areas of the park.
Certain sections of Nahanni are off-limits to outsiders due to their fragile ecosystems or cultural significance to the indigenous Dene. However, some claim that the limits are intended to confine the supernatural powers within the park as much as they are to keep people out.
