The island is long and wide, with its highest elevation above sea level. On the southern end of Dorset Island, at an elevation of above sea level, the mountain, Cape Dorset, projects into the Hudson Strait. It is part of the Kingnait Range. The cape represents the southern tip of the Foxe Peninsula. On September 24, 1631, Captain Luke Foxe named the landform "Cape Dorset" to honour his benefactor, Lord Chamberlain, Edward Sackville, 4th Earl of Dorset. Kingnait Hill, at high, is located on the island's north-west side. The shorter Eegatuak Hill is located north of the cape, on its eastern side, rising above sea level, and exhibiting a distinctive bowl-shape surmounted by a cairn. Mallik Island, directly to the north, is joined to Dorset Island by sand and boulders. A natural harbour exists in the peninsula formed by the southeast side of Mallik Island and the northwest side of Dorset Island with prevailing northwesterly winds at knots, stronger in September and October. The anchorage may have heavy swell conditions and there is frequent fog during the navigation season of early August through mid-October. Ice break-up is around mid-July, and freeze-up occurs in early November. Winter ice thickness can be up to. There are several other islands within, including Ukaliqtuuq and Saqajaa.
History
In 1913, a trading post was established on the island by the Hudson's Bay Company. A Roman Catholic mission was located on Dorset Island during the period of 1938 to 1960. The first discovery of the remains of Dorset culture was on Dorset Island. An ancient Paleo-Eskimo people, they flourished in this area for about 2,000 years, during the period of 1000 BC through 1100 AD. Present-day Dorset Islanders, Inuit who descend from the later Thule culture, refer to Dorset culture people as Tuniit in their legends. In 1947, the Nascopie, a Hudson's Bay Company supply ship was wrecked on the island. Some of the ship was salvaged by the Inuit for building supplies.
Community
Across from Mallik Island, on the northern side of Dorset Island is located the Inuit hamlet of Kinngait. It is approximately north of the mountain cape bearing the same name. Because the people of this community are known for their artisanship, including drawing, printmaking, and carving, the community of Kinngait is commonly referred to as the "Inuit art capital".
