The '''[[Jamesway hut]]''' is a portable and easy-to-assemble hut, designed for polar weather conditions. This version of the Quonset hut was created by James Manufacturing Company of Fort Atkinson, Wisconsin. Insulated blankets in 1.2 m (3 ft 11 in)-wide lengths were made with glass fiber insulation faced with flame-proof muslin and enclosed in plastic-treated cotton that was water-, vermin-, and fire-proof. The hardware (nails, fasteners, and connecting bars) was the only metal component. The whole package weighed 540 kg (1,190 lb) for a 5 meter (16 ft)-square hut. Its wooden packing crates were designed for reuse as the hut floor.
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 storage/floor sections, each 1.2 by 2.4 m (3 ft 11 in by 7 ft 10 in) were made from plywood and insulated with R-7 fiberglass insulation, which provided a portable, warm and cleanable floor. The wooden arches holding up the roof were attached to the floor sections with steel fittings and wing nuts, and were strong enough to hold a winter’s snow. The arches, the key to the design, were curved, glue-laminated wooden 15 cm (6 in) beams on 1.2 m (3 ft 11 in) centers that folded in quarters on steel hinges and removable pins.

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.
