It has been a while, but I’m back! How about an adventure on the World's Largest Uninhabited Island? Um, sure! Devon Island is a remote Island in the Canadian High Arctic. It is primarily covered by ice from the Beltcher Glacier on the East, and the Haughton Impact Crater on the West. The island's landscape is so desolate, it has been used by NASA as the world's best Mars analog site for the practice use of Mars Rovers. Because of the lack of vegetation, extreme weather, and extreme isolation, Devon Island is the largest, uninhabited island in the world.
