Nahanni National Park Reserv is in the Dehcho Region of the Northwest Territories, Canada. The central feature of the park is the South Nahanni River. At Virginia Falls, the river plunges 295 ft in a thunderous plume; it is more than twice the height of Niagara Falls. In the centre of the falls is a dramatic spire of resistant rock, called Mason's Rock. Due to the mist, the immediate vicinity of the falls is home to several rare orchid species. The Dene peoples have used the lands around Nahanni National Park Reserve for thousands of years. The local oral history contains references to the Naha tribe, a mountain-dwelling people who used to raid settlements in the adjacent lowlands. These people are said to have quickly and mysteriously disappeared. Legends of haunted valleys and lost gold emerged after the headless corpses of Métis prospectors Willie and Frank McLeod were found around 1908. The Lost McLeod Mine, a legendary lost mine somewhere in the park, is supposed to have been where the two brothers found their gold. In the years that followed, mysterious deaths of other prospectors added to the legends. The names of park features such as Deadmen Valley, Headless Creek, Headless Range and the Funeral Range, bear testimony to these stories and legends. The have been two types of cryptids reported in the park. The Nuk-luk is a cryptozoological hominid that stands about 5 ft tall, and has a long beard. The waheela is wolf-like creature.
