The Spatsizi Plateau is a plateau in the upper basin of the Stikine River in north-central British Columbia, Canada. Most of the plateau, which is a sub-plateau of the Stikine Plateau, is enshrined in either Spatsizi Plateau Wilderness Provincial Park or Spatsizi Headwaters Provincial Park. It is flanked on the south and southwest by the Skeena Mountains, on the southeast by the Omineca Mountains, on the northeast by the Stikine Ranges of the Cassiar Mountains, and on the west by the Klastline Plateau (another subplateau of the Stikine Plateau).

Name

The name is an adaptation of a phrase in the Sekani language meaning "red goat", a reference to the habit of mountain goats in the area rolling on a particular red-coloured mountain, turning their coats red (tspah=goat, tsije=red).

Geology and terrain

The plateau is a large lava plateau, dissected by river valleys, and contains various small mountain ranges. Both the Stikine and Spatsizi Rivers have their sources in the plateau.

Climate

The climate of the plateau, which is of high altitude, is sub-arctic in nature. Isolated from the moisture of the Pacific Ocean by successive walls of mountains and other plateaus, the Spatsizi is semi-arid in many areas.

Fauna

The Spatsizi Plateau is the range of the largest remaining herd of woodland caribou in British Columbia. Other fauna in the area include mountain goats, moose, grizzlies and wolves.

The Stikine River is a major river in northern British Columbia (BC), Canada and southeastern Alaska in the United States. It drains a large, remote upland area known as the Stikine Country east of the Coast Mountains. Flowing west and south for 610 kilometres (379 mi), it empties into various straits of the Inside Passage near Wrangell, Alaska. About 90 percent of the river's length and 95 percent of its drainage basin are in Canada. Considered one of the last truly wild large rivers in BC, the Stikine flows through a variety of landscapes including boreal forest, steep canyons and wide glacial valleys.

The Skeena River is the second-longest river entirely within British Columbia, Canada. Since ancient times, the Skeena has been an important transportation artery, particularly for the Tsimshian and the Gitxsan—whose names mean "inside the River of Mist" ,and "people of the River of Mist," respectively. The river and its basin sustain a wide variety of fish, wildlife, and vegetation, and communities native to the area depend on the health of the river. The Tsimshian migrated to the Lower Skeena River, and the Gitxsan occupy territory of the Upper Skeena.

British Columbia is the westernmost province of Canada, bordered by the Pacific Ocean. With an area of 944,735 km2 (364,764 sq mi) it is Canada's third-largest province. The province is almost four times the size of the United Kingdom and larger than every United States state except Alaska. It is bounded on the northwest by the U.S. state of Alaska, directly north by Yukon and the Northwest Territories, on the east by Alberta, and on the south by the U.S. states of Washington, Idaho, and Montana. Formerly part of the British Empire, the southern border of British Columbia was established by the 1846 Oregon Treaty. The province is dominated by mountain ranges, among them the Canadian Rockies but dominantly the Coast Mountains, Cassiar Mountains, and the Columbia Mountains. Most of the population is concentrated on the Pacific coast, notably in the area of Vancouver, located on the southwestern tip of the mainland, which is known as the Lower Mainland. It is the most mountainous province of Canada.

Spatsizi Plateau Wilderness Provincial Park is located in the northern portion of British Columbia, Canada, approximately 698, 659 hectares and encompasses the Spatsizi River and Gladys Lake Ecological Reserve. The park is a designated protected area that is intended for the conservation and research on caribou, grizzly bears, fish, and other wildlife species populations. Before the provincial park's establishment in 1975, the area was a historical hunting ground for local Indigenous communities like the Tahltan First Nations. It is the second largest provincial park in British Columbia.

The Omineca Mountains, also known as "the Ominecas", are a group of remote mountain ranges in the Boreal Cordillera of north-central British Columbia, Canada. They are bounded by the Finlay River on the north, the Rocky Mountain Trench on the east, the Nation Lakes on the south, and the upper reaches of the Omineca River on the west. They form a section of the Continental Divide, that, in this region, separates water drainage between the Arctic and Pacific Oceans. The lower course of the Omineca River flows through the heart of the range. To the south of the Ominecas is the Nechako Plateau, to the west the Skeena Mountains and Hazelton Mountains, to the north the Spatsizi Plateau and the Stikine Ranges, while east across the Rocky Mountain Trench are the Muskwa Ranges.

The Grand Canyon of the Stikine is a 72 km (45 mi) stretch of the Stikine River in northern British Columbia, Canada. It has been compared to the Grand Canyon of the Colorado. The canyon is home to a large population of mountain goats and other wildlife. Officially the canyon is described as unnavigable by any watercraft, however there have been numerous successful descents made by expert whitewater paddlers since the first attempt in 1981. Since it was first attempted, the Grand Canyon of the Stikine has maintained a legendary reputation among whitewater experts as the 'Mt. Everest' of big water expedition whitewater boating against which all other navigable rivers are measured.
