The '''[[Beardmore Glacier]]''' in [[Antarctica]] is one of the largest valley [[glacier]]s in the world, being 200 km (125 mi) long and having a width of 40 km (25 mi). It descends about 2,200 m (7,200 ft) from the Antarctic Plateau to the [[Ross Ice Shelf]] and is bordered by the Commonwealth Range of the [[Queen Maud Mountains]] on the eastern side and the Queen Alexandra Range of the Central [[Transantarctic Mountains]].
The '''[[southern elephant seal]]''' is one of the two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season.


The glacier is one of the main passages through the Transantarctic Mountains to the great polar plateau beyond, and was one of the early routes to the [[South Pole]] despite its steep upward incline. The glacier was discovered and climbed by [[Ernest Shackleton]] during his Nimrod Expedition of 1908. Although Shackleton turned back before reaching the [[South Pole]], he established the first proven route towards the pole and, in doing so, became the first person to set foot upon the polar plateau.

The southern elephant seal is one of the two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season.

The world population was estimated at 650,000 animals in the mid-1990s, and was estimated in 2005 at between 664,000 and 740,000 animals. Studies have shown the existence of three geographic subpopulations, one in each of the three oceans. Tracking studies have indicated the routes traveled by elephant seals, demonstrating their main feeding area is at the edge of the Antarctic continent. While elephant seals may come ashore in Antarctica occasionally to rest or to mate, they gather to breed in subantarctic locations.
