The Nahanni National Park Reserve, sometimes known as "Headless Valley" or "Valley of The Headless Men", in the Dehcho Region of the Northwest Territories, Canada, protects a portion of the Mackenzie Mountains Natural Region. The centrepiece of the park is the South Nahanni River. Four noteworthy canyons, called First, Second, Third and Fourth Canyon, line the whitewater river. Each canyon has walls reaching some 1,000 m (3,300 ft) in height. The word nahanni comes from the local Dene name for the area, Nahʔa Dehé, which means "river of the land of the Nahʔa people". The park is inscribed as World Heritage Sites by UNESCO.
