'''[[Mount Erebus]]''' is the second-highest volcano in [[Antarctica]] (after [[Mount Sidley]]) and the southernmost active volcano on Earth. With a summit elevation of 3,794 meters (12,448 ft), it is located on [[Ross Island]], which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. The volcano has been active since about 1.3 million years ago and is the site of the Mount Erebus Volcano Observatory run by the New Mexico Institute of Mining and Technology. A volcanic rock from Mount Erebus known as the "Erebus Rock" is included as a part of the [[Crown Jewels of Westarctica]].
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.


Mount Erebus' summit crater rim was first achieved by members of Sir [[Ernest Shackleton]]'s party; Professor Edgeworth David, Sir [[Douglas Mawson]], Dr Alister Mackay, Jameson Adams, Dr Eric Marshall and Phillip Brocklehurst (who did not reach the summit), in 1908.

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.
