Devon Island

Devon Island in Canada is the largest uninhabited island (no permanent human residents) in the world. It is in Baffin Bay, Qikiqtaaluk Region, Nunavut, Canada. It is one of the largest members of the Arctic Archipelago, the second-largest of the Queen Elizabeth Islands, Canada's sixth-largest island, and the 27th-largest island in the world. It has an area of 55,535.39 km2 (21,442.33 sq mi) (slightly smaller than Croatia). The bedrock is Precambrian gneiss and Paleozoic siltstones and shales. The highest point is the Devon Ice Cap at 1,920 m (6,300 ft) which is part of the Arctic Cordillera. Devon Island contains several small mountain ranges, such as the Treuter Mountains, Haddington Range, and Cunningham Mountains, as well as the Haughton impact crater. The notable similarity of its surface to that of Mars has attracted interest from scientists.
