Devon Island has an area of around 55,247 km² (21,331 miles²). It is part of the Canadian archipelago in the Arctic Circle, to the north of Baffin Island. Around a third of the island is covered with ice while the rest is mostly barren, with glacial meltwater gullies and lakes.
Its most distinctive feature is the Haughton Crater - a 20km-wide impact crater which was formed 23 million years ago. Devon Island is home to the Haughton-Mars Project, in which scientists are using the desolate environment of Devon Island to learn about surviving on Mars.
