Topography of Banks Island

Banks Island is one of the larger members of the Canadian Arctic Archipelago. Situated in the Inuvik Region, and part of the Inuvialuit Settlement Region, of the Northwest Territories, it is separated from Victoria Island to its east by the Prince of Wales Strait and from the mainland by Amundsen Gulf to its south. The Beaufort Sea lies to its west, and to its northeast M'Clure Strait separates the island from Prince Patrick Island and Melville Island.

It is home to barren-ground caribou, polar bears, and birds such as robins and swallows. Over 68,000 muskoxen also live on the island, the majority of the world's population. As of the 2011 census it had a human population of 112, all in Sachs Harbour.[1]

European discovery

Pre-Dorset cultural sites have been found that date from approximately 1500 BCE but European contact came much later. In 1820 it was seen from Melville Island by Sir William Edward Parry and named "Banks Land" in honour of Sir Joseph Banks. However, during the later exploration of the area by the McClure Arctic Expedition the island was marked on their maps as "Baring Island".[2] McClure's ship, the HMS Investigator, was frozen in Prince of Wales Strait. That spring he sent out sledging parties and determined that Banks Island was an island. In the following year he almost circumnavigated the island but was again frozen in at Mercy Bay where he and his crew spent the next three before making their escape across the ice.[3]

The only permanent settlement on the island is the Inuvialuit hamlet of Sachs Harbour (Ikhuak), on the southwest coast.

Description

Banks Island covers an area 70,028 km2 (27,038 sq mi) and it is the world's 24th largest island and Canada's fifth largest island. It is about 380 km (240 mi) long, and at its widest point at the northern end, 290 km (180 mi) across. The highest point of the island is in the south, Durham Heights and rises to about 730 m (2,400 ft).[4] It is part of the Canadian Arctic Archipelago, and had a population of 112 in 2011, all in Sachs Harbour.

Ecology

The island is treeless, with the tallest plant, the Arctic willow, growing occasionally to about the height of a person's knee but usually standing no taller than 10 cm (3.9 in).

Banks Island is home to two-thirds of the world's population of lesser snow geese, which make their way across the Amundsen Gulf from the mainland. There is an annual goose hunt in the spring out of Sachs Harbour. The island is part of the tundra world biome, which has extremely cold winters. The island is home to barren-ground caribou, polar bears, muskoxen, and birds such as robins and swallows. Over 68,000 muskoxen live on the island, the majority of the world's population.

Two federal migratory bird sanctuaries were founded on the island in 1961.

Aulavik National Park of Canada, a fly-in park, protects about 12,274 km2 (4,739 sq mi) of Arctic lowlands at the northern end of the island.[5] The park has the highest concentration of muskoxen on earth, and is home to the endangered Peary caribou.[5] The Thomsen River runs through the park, and is the northernmost navigable river (by canoe) in North America. Ptarmigan and ravens are considered the only year-round birds in the park, although 43 species make seasonal use of the area. In Inuvialuktun Aulavik means "place where people travel" and the "wildlife and land have supported aboriginal peoples for more than 3,400 years, from Pre-Dorset cultures to contemporary Inuvialuit."[5]

The first confirmed grizzly–polar bear hybrid found in the wild was shot on Banks Island in April 2006, near Sachs Harbour.

HMS Investigator

In July 2010, Parks Canada archaeologists looking for HMS Investigator found it 15 minutes after they started a sonar scan of Banks Island's Mercy Bay. The archaeology crew has no plans to raise the ship. They will do a thorough sonar scan of the area, then send a remotely operated vehicle.[6]
