The Beaufort Sea is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, the Yukon, and Alaska, and west of Canada's Arctic islands. The sea is named after Sir Francis Beaufort, a hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea's shores.
Great Bear Lake is a lake in the boreal forest of Canada. It is the largest lake entirely in Canada, the fourth-largest in North America, and the ninth-largest in the world. The lake is in the Northwest Territories, on the Arctic Circle between 65 and 67 degrees of northern latitude and between 118 and 123 degrees western longitude, 156 m (512 ft) above sea level.
The Anderson River is in the Northwest Territories in northern Canada. It originates in lakes northwest of Great Bear Lake; its headwaters are possibly on the north side of Colville Lake in the vicinity of the hamlet of Colville Lake. It flows north and west in the area between the Mackenzie and Coppermine Rivers. Its mouth is on the Beaufort Sea on the Arctic Ocean near the eastern end of Liverpool Bay at about 70 degrees north latitude. Its main tributary is the Carnwath River. Originally known as the Beghula River it was renamed to the Anderson River in 1857 by Roderick MacFarlane after James Anderson, both of the Hudson's Bay Company. Anderson was the Chief Factor in the Mackenzie District.

Volcanism of Northern Canada has produced hundreds of volcanic areas and extensive lava formations across Northern Canada. The region's different volcano and lava types originate from different tectonic settings and types of volcanic eruptions, ranging from passive lava eruptions to violent explosive eruptions. Northern Canada has a record of very large volumes of magmatic rock called large igneous provinces. They are represented by deep-level plumbing systems consisting of giant dike swarms, sill provinces and layered intrusions.
The Coppermine River Group is a sequence of Mesoproterozoic continental flood basalts forming part of the Mackenzie Large Igneous Province in the Northwest Territories and Nunavut, Canada. It is among the largest flood basalt provinces on Earth, covering the area with a volume of approximately 650,000 km3 (155,943 cu mi).
The Mackenzie Large Igneous Province (MLIP) is a major Mesoproterozoic large igneous province of the southwestern, western and northwestern Canadian Shield in Canada. It consists of a group of related igneous rocks that were formed during a massive igneous event starting about 1,270 million years ago. The large igneous province extends from the Arctic in Nunavut to near the Great Lakes in Northwestern Ontario where it meets with the smaller Matachewan dike swarm. Included in the Mackenzie Large Igneous Province are the large Muskox layered intrusion, the Coppermine River flood basalt sequence and the massive northwesterly trending Mackenzie dike swarm.
The Taltson River is a roughly 500 km (310 mi) river in the Northwest Territories of Canada that drains into the Great Slave Lake. There are three hydroelectric power control structures on the river, and one power station.

It is a tributary of the Mackenzie River, joining it on the left bank some 100 kilometres (62 mi) north of Wrigley. Draining a rugged and high area of the Mackenzie Mountains, the Redstone watershed is sparsely populated by people but remains an ecological haven for wildlife including moose, caribou, wolves Dall's Sheep and Bears. It is a pristine mountain wilderness.
The Whitefish River is a river in the Deline District, Sahtu Region, Northwest Territories, Canada. It is in the Arctic Ocean and Mackenzie River drainage basins, is a tributary of Great Bear Lake and has a watershed of 4,740 square kilometres (1,830 sq mi).
