Canada has a vast geography that occupies much of the continent of North America, sharing a land border with the contiguous United States to the south and the U.S. state of Alaska to the northwest. Canada stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west; to the north lies the Arctic Ocean. Greenland is to the northeast with a shared border on Hans Island. To the southeast Canada shares a maritime boundary with France's overseas collectivity of Saint Pierre and Miquelon, the last vestige of New France. By total area, Canada is the second-largest country in the world, after Russia. By land area alone, however, Canada ranks fourth, the difference being due to it having the world's largest proportion of fresh water lakes. Of Canada's thirteen provinces and territories, only two are landlocked while the other eleven all directly border one of three oceans.
The Continental Divide of the Americas is the principal, and largely mountainous, hydrological divide of the Americas. The Continental Divide extends from the Bering Strait to the Strait of Magellan, and separates the watersheds that drain into the Pacific Ocean from those river systems that drain into the Atlantic and Arctic Ocean, including those that drain into the Gulf of Mexico, the Caribbean Sea, and Hudson Bay.
The Mackenzie River is a river in the Canadian boreal forest. It forms, along with the Slave, Peace, and Finlay, the longest river system in Canada, and includes the second largest drainage basin of any North American river after the Mississippi.
Alberta is one of the thirteen provinces and territories of Canada. Located in Western Canada, the province has an area of 661,190 km2 (255,290 sq mi) and is bounded to the south by the United States state of Montana along 49° north for 298 km (185 mi); to the east at 110° west by the province of Saskatchewan for 1,223 km (760 mi); and at 60° north the Northwest Territories for 644 km (400 mi).

Along with Saskatchewan it is one of only two landlocked provinces or territories.
Lake Athabasca is in the north-west corner of Saskatchewan and the north-east corner of Alberta between 58° and 60° N in Canada. The lake is 26% in Alberta and 74% in Saskatchewan.

The Fond du Lac River is one of the upper branches of the Mackenzie River system, draining into the Arctic Ocean, located in northern Saskatchewan, Canada. The river is 277 kilometres (172 mi) long, has a watershed of 66,800 km2 (25,800 sq mi), and its mean discharge is 300 m3/s (11,000 cu ft/s).
The Clearwater River is located in the Canadian provinces of Saskatchewan and Alberta. It rises in the northern forest region of north-western Saskatchewan and joins the Athabasca River in north-eastern Alberta. It was part of an important trade route during the fur trade era and has been designated as a Canadian Heritage River.
Triple Divide Peak is located in the Lewis Range, part of the Rocky Mountains in North America. The peak is a feature of Glacier National Park in the state of Montana in the United States. The summit of the peak, the hydrological apex of the North American continent, is the point where two of the principal continental divides in North America converge, the Continental Divide of the Americas and the Northern or Laurentian Divide.
Westlock County is a municipal district in central Alberta, Canada that is north of Edmonton. The county was formerly known as the Municipal District of Westlock No. 92, and was created in 1943 from the merger of five smaller municipal districts.
Lac La Biche is a large lake in north-central Alberta, Canada. It is located along the Northern Woods and Water Route, 95 km east of Athabasca. Lac La Biche has a total area of 236 km2 (91 sq mi), including 3.2 km2 (1.2 sq mi) islands area.
Beaver River is a large river in east-central Alberta and central Saskatchewan, Canada. It flows east through Alberta and Saskatchewan and then turns sharply north to flow into Lac Île-à-la-Crosse on the Churchill River which flows into Hudson Bay.
Wollaston Lake is a lake in north-eastern part of the Canadian province of Saskatchewan. It is about 550 kilometres (340 mi) north-east of Prince Albert. With a surface area of 2,286 square kilometres (883 sq mi), it is the largest bifurcation lake in the world – that is, a lake that drains naturally in two directions.
Last Mountain Lake, also known as Long Lake, is a prairie lake formed from glaciation 11,000 years ago. It is located in south central Saskatchewan, Canada, about 40 kilometres (25 mi) north-west of the city of Regina. It flows into the Qu'Appelle River via Last Mountain Creek, which flows past Craven. It is approximately 93 km (58 mi) long, and 3 km (1.9 mi) wide at its widest point. It is the largest naturally occurring body of water in southern Saskatchewan. Only Lake Diefenbaker, which is man-made, is larger. The lake is a popular resort area for residents of south-eastern Saskatchewan.
A lake bifurcation occurs when a lake has outflows into two different drainage basins. In this case, the drainage divide cannot be defined exactly, as it is situated in the middle of the lake.
Geikie River is a river in the northern part of the Canadian province of Saskatchewan. The river's source is Costigan Lake, which is near the uranium producing areas around the Key Lake mine in the Athabasca Basin. It flows in a north-easterly direction and flows into Wollaston Lake.
The Athabasca Landing Trail was a long-distance portage route that linked Fort Edmonton on the North Saskatchewan River with Athabasca Landing on the Athabasca River. The distance of the trail between Fort Edmonton and Athabasca Landing was 100 miles (160 km), giving the trail the nickname "The 100 Mile Portage."
