Devon Island is one of the bigger members of the Canadian Arctic Archipelago. It is the second-biggest of the Queen Elizabeth Islands, Nunavut, Canada, the 27th biggest island in the world, Canada's 6th biggest island and the biggest island in the world where nobody lives on. Devon Island has an area of 55,247 km2 (21,331 sq mi). The highest point is the Devon Ice Cap at 6,299 ft/1,920 metres which is part of the Arctic Cordillera. Devon Island has many small mountain ranges, such as the Treuter Mountains, Haddington Range and the Cunningham Mountains.
Devon Island is also notable for having the Haughton impact crater, made some 39 million years ago when a meteorite about 2 km (1.2 mi) in diameter crashed into what were then forests. The impact left a crater about 23 km (14 mi) in diameter, which was a lake for several million years.
