The light tan peninsula near the center of this image is part of Baffin Island, part of  the Canadian Arctic Archipelago, in the territory of Nunavut. Above Baffin Island is Devon Island, whose notable feature is the bright white Devon Ice Cap.

Moving east, Baffin Bay is mostly covered by clouds. Some of these have taken on the swirled form of a vortex, as can be observed in the close-up.

Below Baffin Island, part of mainland Nunavut can be seen. The large, sediment-laden, greenish body of water in the lower left quadrant is Rasmussen Basin, a natural waterway through the Canadian Arctic Archipelago. It separates King William Island (to the north-west) from the mainland.

To the east of this basin is Pelly Bay, a natural inlet and an arm of the Gulf of Boothia. Like Rasmussen Basin, it also appears greenish, although this coloration is limited to its southern reaches.

Devon Island, Canada - January 26th, 2009

One of the larger members of the Canadian Arctic Archipelago, Devon Island is the second-largest of the Queen Elizabeth Islands, Nunavut, Canada, and Canada’s 6th largest island.

The largest uninhabited island on Earth, Devon Island comprises 55,247 km2 (21,331 sq mi) of Precambrian gneiss and Paleozoic siltstones and shales.

The highest point is the Devon Ice Cap at 1,920 m (6,300 ft) which is part of the Arctic Cordillera. Devon Island contains several small mountain ranges, such as the Treuter Mountains, Haddington Range and the Cunningham Mountains. The terrain visible here is predominately mountainous.

Because of its relatively high elevation and its extreme northern latitude, it supports only a meagre population of musk oxen and small birds and mammals. Animal life is concentrated in the Truelove Lowland area of the island, which has a favourable microclimate and supports relatively lush Arctic vegetation.

Temperatures during the brief (40 to 55 days) growing season seldom exceed 10 °C (50 °F), and in winter can plunge to as low as −50 °C (−58 °F). With a polar desert ecology, Devon Island receives very little precipitation. A dusting of snow can be see atop the mountains in the center.
