Not all deserted islands are located in the tropics. In fact, the largest uninhabited island in the world is located in the Arctic. Canada's Devon Island sits in Baffin Bay. People have lived on Devon in the past: it was a fur-trading outpost, and there have been several Inuit settlements. However, the last of these people left more than 50 years ago. The topography is such that the island has been used by astronauts to test equipment and to train for future missions to Mars. Devon's austerely beautiful landscapes are also home to musk oxen and bird species. Plant life thrives in the island's lowland areas, which have a microclimate that features more hospitable conditions compared to the windswept highlands and coastal areas. Camping expeditions are possible on Devon, though visiting without the support of an outfitter is not advisable.
