Definition

Devon Island (federal territory of Nunavut) is a large (66,800 km2), uninhabited island of the Canadian Arctic Archipelago. Situated in a polar desert, Devon Island is considered to be an analogue to Mars because it is cold, dry, and largely non-vegetated, with a variety of analogous geological and geomorphologic features. These include the well-exposed and preserved Haughton impact crater and associated impact-induced hydrothermal deposits, as well as intracrater paleolake deposits, alteration minerals, valleys and gullies, and polygonal ground. In addition, the biological characteristics (e.g., endolithic and extremophilic microorganisms, little to no vegetation, low nutrients, and organic biomarkers in impacted rocks) are of particular interest to astrobiologists.
