Ellesmere Island is the most northern island in Canada. Ellesmere lies northwest of Greenland and is the world's 10th biggest island. And, sticking out of glaciers, is the one and only, Barbeau Peak. Barbeau Peak is the highest mountain east of the Rockies, while the Rockies lie in North America. Around the island's edges, wide ice shelves, or ledges of sea ice attached to land, are ending their legend. What I mean by this is that, climate change has caused some ice shelves that have hung for more than 3,000 years, to break off and float away in the ocean.
What is the largest uninhabited island in the world? It's called Devon Island and its in Canada. It has several small mountain ranges. The highest peak is at 6,300 ft and that is apart of the Arctic Cordillera. Some people claim that it is the Mars of Earth! It is very desert-like with some icy and polar parts.
The sheer cliffs of Eldey Island is home to a huge number of birds, including one of the biggest northern gannet colonies in the world, with around 16,000 pairs. The island formerly supported the last remnant flightless great auk population, which went extinct in 1844 unfortunately.
