Geography

There are several different landforms in the park that have taken millions of years to form, and give it a diversity not seen in any other national park in Canada. Sediment left by an ancient inland sea 500-200 million years ago had since become pressed into layers of rock. These layers were stacked about 6 km deep and are peppered with fossils, remnants of these ancient sea beds. As the continents shifted, the North American and Pacific plates collided, the force of which pushed the layers of rock upwards. Ridges of rock bent and broke, leaving behind the ranges seen today. This same action also caused volcanic activity, sending molten lava into but not through the sedimentary rock. While there are no volcanoes in the park, towers of heated rock called igneous batholiths were sent upwards, pushing the sediment further up. The top layer of sedimentary rock was eventually eroded away, resulting in granite towers that form the Ragged Range.

Over the last 2 million years, glaciers have covered most of North America, creating most of the land formations seen today. While previous ice ages affected the Park area, the most recent, the Wisconsin Ice Age (85,000-10,000 years ago) touched only the most western and eastern parts of the Park. This has left many geological features in the park much more time to develop than most of North America had.

The central feature of the park is the South Nahanni River which runs the length of the park, beginning near Moose Ponds

 and ending when it meets the Liard river near Nahanni Butte. The South Nahanni is a rare example of an antecedent river. The mountains rose slowly enough, and the river was powerful enough that the river maintained its course over its history, meaning it has the same path today as it did before the mountains rose. As the river was meandering, the canyons it carved also meander. Most visitors only visit the portions from Virginia Falls down.

There are four main canyons that line the south Nahanni river, named by prospectors, numbering them as they travelled up the river. The fourth canyon begins with Virginia Falls, and was created as the falls eroded the limestone surrounding the river, working its way upstream. It is five miles long. Third canyon runs through Funeral Range, around 40 km long. Because its walls are composed of a stratum of shale, sandstones and limestone this canyon has long slopes instead of steep, flat walls like the lower canyons. Big bend, a point where the river does a 45 degree turn, marks the end of Third and the beginning of Second Canyon. At 15 km long, it runs through the Headless Range. The final canyon is considered the most beautiful. Beginning after Deadman Valley, First Canyon boasts the highest, most vertical walls, cutting through very resistant limestone. It ends near Kraus Hotsprings, making it about 30 km long. Following this, the river slows and braids into different channels, passing through the Park boundary, and coming together again near the village of Nahanni Butte. Soon after the town, the South Nahanni River joins the Liard river.

Tufa Mounds

The Rabbitkettle Tufa Mounds are the largest of tufa mounds in Canada. The largest of the mounds is 27m high and 74m across. The source of the springs comes from deep in the earths crust, near the base of the granite batholiths that form the Ragged Range. The volcanic activity that raised the mountains still heats the water deep below the surface of the earth. The heated water percolates upwards, dissolving calcium carbonate from limestone deposits on its way by. When it reaches the surface springs, the water cools and the calcium carbonate particles are released. These microscopic particles settle to form porous calcite rims around the pools of water. These pools range in size from bathtub to fingernail size. This process takes a great deal of time, and it is believed that the mounds themselves are around 10, 000 years old, their creation beginning at the end of the last ice age.
These rare and fragile features are protected as a Zone 1, Special Preservation Area, and all visitors must be accompanied by Parks Canada Staff in order to minimize impact.

History

Dene peoples have used the lands around Nahanni National Park Reserve for thousands of years. The first human occupation of the area is estimated to have occurred 9,000-10,000 years ago. Evidence of prehistoric human use has been found at Yohin Lake and a few other sites within the park. The local oral history contains many references to the Naha tribe, a mountain-dwelling people who used to raid settlements in the adjacent lowlands. These people are said to have rather quickly and mysteriously disappeared.

First contact with European fur traders expanding into the region occurred in the 18th century, and was increased with Alexander Mackenzie's exploration of the Mackenzie River (Deh Cho), and building of trading posts at Fort Simpson and Fort Liard. During the 19th century, most Dene families left their nomadic lifestyles and settled into more permanent communities, often close to the trading posts. Permanent settlements were established at locations such as Nahanni Butte, Fort Liard and Fort Simpson.

In the late 19th century, the Mountain Indians of the Nahanni region would travel down the Nahanni River each spring in mooseskin boats to trade the winter take of furs. These boats, based on the Hudson Bay York boats, were up to 20 metres in length. Constructed from six to ten untanned moose hides sewn together and stretched over a spruce pole frame, these boats would transport entire families, their dogs and cargo of furs down the river during high water. Upon arrival the boat was dismantled and the hides traded along with the furs. Following a visit to the forts, these people would return to the high country with only what they could carry on their pack dogs.

The stories of the Naha, and dangerous landscape that they inhabited, grew in stature with the Klondike gold rush as some explorers attempted to use the Nahanni as a path to the famous gold fields of the Yukon, or make their fortune on the Flat and South Nahanni rivers. Although no significant gold was found, legends of haunted valleys and lost gold emerged after the headless corpses of Métis prospectors Willie and Frank McLeod were found around 1908. 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.

In 1964, explorer parachutist Jean Poirel from Montreal jumped at its source 500 km North of Yellowknife, followed by his teammate Bertrand Bordet. Jean Poirel imagined the idea of going down the river with inflatable dinghies, opening the path to a new “rafting” sport. During the following four consecutive expeditions in the valley Jean Poirel discovered more than 250 caverns. The most important contained 116 Dall sheep’s skeletons (carbon-14 dated to 2500 years Bc); Jean Poirel named it "Valerie Cavern" after his daughter. He took topographic notes and drew detailed maps, paving the way for the park's creation. During his last expedition in 1972, he escorted Pierre Trudeau, who came in person to estimate this superb and fascinating region.

Park history

Originally established in 1972, by then Prime Minister Pierre Elliot Trudeau, the park was 4766 km² (1,840 sq mi) in area. The park was in "reserve" status pending settlement of outstanding Aboriginal land claims in the region. In 2003, an agreement between the Dehcho First Nations

 gave temporary protection to 23000 km² (8,880 sq mi). In August 2007, the federal government added an extra 5400 km² (2,085 sq mi).

In a novel form of cooperation between federal government and native groups, the Naha Dehe Consensus Team was formed in June 2000 by Canada and the Dehcho First Nations. Their original main tasks included:
1. prepare an Ecological Integrity Statement,
2. complete a review of the Park Management Plan,
3. prepare an Interim Park Management Arrangement, and
4. prepare a Memorandum of Understanding Respecting Park Expansion.
In 2003, these were completed and the purpose of the team changed, now dealing with cooperative management issues, according to the Interim Park Management Arrangement, until the Dehcho Process is completed.

, announced legislation that will increase the area of Nahanni National Park to cover 30050 km² (11,602 sq mi), including 91% of the Greater Nahanni ecosystem in the Dehcho region and most of the South Nahanni River watershed.

The new park area is estimated to be the home of around 500 grizzly bears, two herds of woodland caribou, as well as species of alpine sheep and goats and other species. The new boundary will include the highest mountains and largest ice fields in the Northwest Territories. With the expansion of the park there have been several added designated landing sites. because most access to the park is done by aircraft and air access is restricted in the park, there are a set amount of places aircraft can land. Before the expansion these were limited to Virginia Falls and Rabbitkettle Lake. Now there are five more; the Bunny Bar, Island Lake, Honeymoon Lake, Glacier Lake, and Seaplane Lake. However, only Virginia Falls and Glacier Lake are designated for Day use visittation, meaning all other sites require visitors to stay overnight in the park.

 in 1978. The South Nahanni River achieved Canadian Heritage River status in 1987. Presently around 800–1000 people visit the park every year, most of which are overnight visitors who travel down the South Nahanni. The park is open year round, but most visitors come in June, July, and August. Virginia falls is the only area of the park where a reservation is required, which must be done months in advance to prevent overcrowding. For safety reasons, all visitors must register with Park officials upon entering the Park boundarys, and degregister within 24 hours of leaving. There is a park office in Nahanni Butte at the end of the river, where visitors can deregister. The only practical way to get to Nahanni National Park is by floatplane or by helicopter, usually from Fort Simpson but other communities and locations offering a gateway into the park include: Watson Lake
