Coats Island

Coats Island (Inuktitut: Akpatordjuark) lies at the northern end of Hudson Bay in the Kivalliq Region of Nunavut. At 5,498 km² (2,123 sq mi) in size, it is the 107th largest island in the world, and Canada's 24th largest island.

The island has areas of federal crown land and areas of private land owned by Inuit, however, the last permanent residents left in the 1970s. With no permanent settlements, the island is also the largest uninhabited island in the northern hemisphere south of the Arctic Circle. It was the last home of the Sadlermiut people who are widely believed to represent the Dorset culture.

Geography

Coats Island is 130 km (81 mi) long. It reaches a maximum elevation of 185 m above sea level. This high point occurs along the rocky northern perimeter between Cape Pembroke and Cape Prefontaine. The underlying rocks in this area are Precambrian metamorphics. Less than 5% of the island is more than 100 m (330 ft) above sea level. The southern half of the island is primarily low-lying muskeg and made up of Palaeozoic sedimentary rocks, such as limestone and sandstone.
