'''[[Toney Mountain]]''' is an elongated [[snow]]-covered shield volcano, 60 km (38 mi) long and rising to 3,595 meters at Richmond Peak, located 56 km (35 mi) southwest of [[Kohler Range]] in [[Westarctica]].

Toney Mountain lies in a tectonically and volcanically active region of [[Antarctica]]. There, a layer of basaltic rocks up to 5 kilometers (3.1 mi) thick underlie a series of felsic volcanic edifices. These basaltic rocks in turn are emplaced above a Paleozoic basement with granite intrusions of Devonian-Cretaceous, which crops out in some mountain ranges. Beneath Toney Mountain, the basaltic floor rises from an elevation of 3 kilometers (1.9 mi) beneath sea level, and the volcano is situated on the floor of a graben. The region is further characterized by a 500 by 1,200 kilometers (310 mi × 750 mi) large dome-like uplift, part of the West Antarctic Rift, and it may reflect the presence of a stationary hotspot.

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.
