Jøkulhest Dome
Jøkulhest Dome () is the high icecapped summit of Jokulkyrkja Mountain, in the Mühlig-Hofmann Mountains of Queen Maud Land, Antarctica. It was plotted from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named Jøkulhest (the glacier A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight.

Mühlig-Hofmann Mountains
The Mühlig-Hofmann Mountains (german: Mühlig-Hofmann-Gebirge) is a major group of associated mountain features extending east to west for between the Gjelsvik Mountains and the Orvin Mountains in Queen Maud Land, East Antarctica. With its summit at , the massive Jøkulkyrkja Mountain forms the highest point in the Mühlig-Hofmann Mountains. Discovery and naming The Mühlig-Hofmann Mountains were discovered by the Third German Antarctic Expedition (1938-1939), led by Capt. Alfred Ritscher, and named for the division director of the German Air Ministry. They were remapped by the Norwegian Antarctic Expedition, 1956-1960.

Queen Maud Land
Queen Maud Land ( no, Dronning Maud Land) is a roughly region of Antarctica claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20° west and the Australian Antarctic Territory 45° east. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian queen Maud of Wales (1869–1938). In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of two Antarctic claims made by Norway, the other being Peter I Island. They are administered by the Polar Affairs Department of the Norwegian Ministry of Justice and Public Security in Oslo. Most of the territory is covered by the east Antarctic ic ...

Sixth Norwegian Antarctic Expedition
The sixth Norwegian Antarctic Expedition (''Den norske antarktisekspedisjonen'') was a scientific expedition to Queen Maud Land in Antarctica. The expedition was based at Norway Station () which was located on the Fimbul Ice Shelf bordering the coast of Queen Maud Land. The expedition carried out survey work and scientific studies over a period of three-four years (1956–1960). The expedition was intended as part of Norway's participation in the International Geophysical Year, 1957-58. The crew set sail from Oslo on board two whaling ships, the ''Polarsirkel'' and ''Polarbjørn'', on 10 November 1956. The expedition was led by Sigurd Gunnarson Helle, a geodesist at Norsk Polarinstitutt. It included a total crew of fourteen researchers which was reduced to nine during the third year. Among their activities were topological mapping of the region. In 1960, King Olav V of Norway instituted the Antarctic Medal The Antarctic Medal is a civil decoration of Norway. Established by ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Mountains Of Queen Maud Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...
