Lying north of mainland Canada, the Arctic Archipelago consists of 94 major islands (greater than 130 km2) and 36,469 minor islands covering a total of 1.4 million km2. Apart from Greenland, which is almost entirely ice covered, the Canadian Arctic Archipelago forms the world's largest High Arctic land area.
La Grosse Île, or Île de Quarantaine, 2.9 km long by 1 km wide, is located 46 km downstream from Québec City in the ST LAWRENCE RIVER estuary. The island is a wooded Appalachian ridge sculpted by coves and capes. In 1646 the Île de Grâce was ceded to Governor Charles Huault de MONTMAGNY.
Circulation is generally anticlockwise; off Greenland, relatively warm, salty water moves north, while along Baffin Island, cold, fresher water originating from the Arctic Ocean flows south. Icebergs, formed by calving off the Greenland glaciers, appear year-round, but are most numerous in August.
Located on the Cumberland Peninsula of Baffin Island, Nunavut, Auyuittuq National Park (established 2001, 19 089 km2) was Canada's first national park located north of the Arctic Circle. It was first set up as a national park reserve in 1976 and established as a national park through the Nunavut Land Claims Agreement.
Attawapiskat River, 748 km long, formed by the confluence of the Pineimuta, Trading and Otoskwin rivers at Attawapiskat Lake, in northeastern Ontario, flows east, jogs north and runs east to the flatland by James Bay. Its drainage area is 50 200 km2 and its mean discharge 626 m3/s.
