⭐ Core Definition: Ellsworth Mountains

The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a 350 km (217 mi) long and 48 km (30 mi) wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson (4,892 meters (16,050 ft)) constituting the highest point on the continent. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones.

Ellsworth Mountains in the context of Ellsworth Land

Ellsworth Land is a portion of the Antarctic continent bounded on the west by Marie Byrd Land, on the north by the Bellingshausen Sea, on the northeast by the base of the Antarctic Peninsula, and on the east by the western margin of the Filchner–Ronne Ice Shelf. It extends between 103°24'W and 79°45'W. The area west of 90°W is unclaimed, the area between 84°W and 90°W is claimed by Chile only, and the remainder by Chile and the United Kingdom as a part of the British Antarctic Territory. Eights Coast stretches between 103°24'W and 89°35'W, and Bryan Coast between 89°35'W and 79°45'W.

It is largely a high ice plateau, but includes the Ellsworth Mountains and a number of scattered mountain groups: Hudson, Jones, Behrendt, Hauberg, Merrick, Sweeney and Scaife Mountains.

Ellsworth Mountains in the context of Vit Ice Piedmont

Vit Ice Piedmont (Bulgarian: ледник Вит, romanizedlednik Vit, IPA: [ˈlɛdniɡ ˈvit]) is the glacier extending 12 km in north-south direction and 6 km in east-west direction in Sostra Heights on the east side of northern Sentinel Range in Ellsworth Mountains, Antarctica. It is situated north of the end of Embree Glacier, east of Bracken Peak, southwest of Anchialus Glacier and south of the end of Newcomer Glacier. The glacier flows eastwards into Rutford Ice Stream.

The glacier is named after Vit River in Northern Bulgaria.

Ellsworth Mountains in the context of Cape Fold Belt

The Cape Fold Belt (CFB) is a 1,300 kilometres (810 mi) long fold-and-thrust mountain belt along the western and southern coastlines of Western Cape, South Africa. The Cape Fold Belt formed during the Permian period (300 to 250 million years ago) in the late Paleozoic age, affecting the sequence of sedimentary rock layers of the siliciclastic Cape Supergroup with folding and faulted rocks, which were deposited in the Cape Basin in the southwestern corner of South Africa.

The Cape Fold Belt was once part of a larger orogenic belt with other mountain ranges that formed as part of the same tectonic event that originally extended from Argentina, across southern Africa, and into Antarctica. It included the Ventana Mountains near Bahía Blanca in Argentina, the Pensacola Mountains in East Antarctica, the Ellsworth Mountains in West Antarctica, and the Hunter–Bowen orogeny in eastern Australia. The rocks involved in this fold system are primarily sandstones and shales, with shales from the Bokkeveld Group persisting in valley floors, while the more erosion-resistant sandstones of the Peninsula Formation form the parallel ranges of the Cape Fold Mountains. The highest peak in the range is Seweweekspoortpiek, which reaches 2,325 meters.
