Geography of Nunavut
The Canadian territory of Nunavut lies mainly in the North American Arctic and covers about of land and water including part of the mainland, most of the islands in the Arctic Archipelago, and all of the islands in Hudson Bay, James Bay, and Ungava Bay which belonged to the Northwest Territories before Nunavut was split from them on 1 April 1999.
This makes it the fifth largest country subdivision in the world. If Nunavut were a country, it would rank 13th in area, after Saudi Arabia. Nunavut has land borders with Manitoba, the Northwest Territories on several islands as well as the mainland, and a tiny land border with Newfoundland and Labrador on Killiniq Island.
Additionally, Nunavut has a land border with Greenland on Hans Island, making it the only Canadian jurisdiction to have a land border with a country other than the United States.
Physical geography
The mountains on the easternmost coasts of Nunavut are part of the Arctic Cordillera which stretches from northernmost Ellesmere Island to the northernmost tip of Labrador.The highest point is Barbeau Peak which offers some of the world's most spectacular scenery.
Geologically, Nunavut lies on the Canadian Shield, with very thin soil lying on top of the bedrock, and many bare outcrops. The multitude of rivers and lakes in the entire region is caused by the watersheds of the area being so young and in a state of sorting themselves out with the added effect of post-glacial rebound. Virtually all of Nunavut's rivers drain into the Arctic Ocean or Hudson Bay, an inland sea of the Arctic Ocean.
Arctic tundra covers virtually all of Nunavut, the only exceptions being the area roughly between the Four Corners and Ennadai and Nueltin lakes, where a marginal taiga or boreal forest exists, and small zones of permanent ice caps, found on some of the larger Arctic islands at sites having a relatively high elevation. Nunavut's vegetation is partially composed of rare berries, lichens, Arctic willows, mosses, tough grass, dwarf shrubs, graminoids, and herbs.
