Mount Raymond
Mount Raymond () is a rock peak, 2,820 m, standing on the southernmost ridge of the Grosvenor Mountains, 2.5 nautical miles (4.6 km) southeast of Mount Cecily. Discovered by Ernest Shackleton of the British Antarctic Expedition (1907–09), who named this feature for his eldest son. The position agrees with that shown on Shackleton's map, but the peak does not lie in the Dominion Range as he thought, being separated from that range by Mill Glacier Mill Glacier is a tributary glacier, wide, flowing northwest between the Dominion Range and the Supporters Range into Beardmore Glacier, Antarctica. It was discovered by the British Antarctic Expedition, 1907–09, and named for Hugh Robert Mill .... Mountains of the Ross Dependency Dufek Coast {{DufekCoast-geo-stub ...

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Grosvenor Mountains
The Grosvenor Mountains () are a group of widely scattered mountains and nunataks rising above the Antarctic polar plateau east of the head of Mill Glacier, extending from Mount Pratt in the north to the Mount Raymond area in the south, and from Otway Massif in the northwest to Larkman Nunatak in the southeast. They were discovered by Rear Admiral Richard E. Byrd on the Byrd Antarctic Expedition flight to the South Pole in November 1929, and named by him for Gilbert Hovey Grosvenor, President of the National Geographic Society, which helped finance the expedition. Several peaks near Mount Raymond were apparently observed by Ernest Shackleton in 1908, although they were then considered to be a continuation of the Dominion Range. Features Geographical features include: * Aitken Nunatak * Block Peak * Hayman Nunataks * Hayman * Johnston Heights * Larkman Nunatak * Mauger Nunatak * Mount Block * Mount Bumstead * Mount Cecily * Mount Pratt * Mount Raymond * Otway Massif Otwa ...

Mount Cecily
Mount Cecily () is a prominent peak, high, standing northwest of Mount Raymond, in the Grosvenor Mountains. It was discovered by the British Antarctic Expedition, 1907–09, and named for Shackleton's daughter. The position agrees with that shown on Shackleton's map but the peak does not lie in the Dominion Range as he thought, being separated from that range by the Mill Glacier Mill Glacier is a tributary glacier, wide, flowing northwest between the Dominion Range and the Supporters Range into Beardmore Glacier, Antarctica.

Ernest Shackleton
Sir Ernest Henry Shackleton (15 February 1874 – 5 January 1922) was an Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic. He was one of the principal figures of the period known as the Heroic Age of Antarctic Exploration. Born in Kilkea, County Kildare, Ireland, Shackleton and his Anglo-Irish family moved to Sydenham in suburban south London when he was ten. Shackleton's first experience of the polar regions was as third officer on Captain Robert Falcon Scott's ''Discovery'' expedition of 1901–1904, from which he was sent home early on health grounds, after he and his companions Scott and Edward Adrian Wilson set a new southern record by marching to latitude 82°S. During the ''Nimrod'' expedition of 1907–1909, he and three companions established a new record Farthest South latitude at 88°S, only 97 geographical miles (112 statute miles or 180 kilometres) from the South Pole, the largest advance to the pole in ...

British Antarctic Expedition, 1907–09
The ''Nimrod'' Expedition of 1907–1909, otherwise known as the British Antarctic Expedition, was the first of three successful expeditions to the Antarctic led by Ernest Shackleton and his second expedition to the Antarctic. Its main target, among a range of geographical and scientific objectives, was to be first to the South Pole. This was not attained, but the expedition's southern march reached a Farthest South latitude of 88° 23' S, just from the pole. This was by far the longest southern polar journey to that date and a record convergence on either Pole. A separate group led by Welsh Australian geology professor Edgeworth David reached the estimated location of the South Magnetic Pole, and the expedition also achieved the first ascent of Mount Erebus, Antarctica's second highest volcano. The expedition lacked governmental or institutional support, and relied on private loans and individual contributions. It was beset by financial problems and its preparation ...

Dominion Range
The Dominion Range () is a broad mountain range, about long, forming a prominent salient at the juncture of the Beardmore and Mill glaciers in Antarctica. The range is part of the Queen Maud Mountains The range was discovered by the British Antarctic Expedition (1907–09) and named by Shackleton for the Dominion of New Zealand, which generously aided the expedition. The highest peak is Mount Mills at . Key geological features Mount Mills Mount Mills () is the highest mountain in the range at , forming part of the northern escarpment overlooking the Beardmore Glacier 13 km north of Mount Saunders. The mountain was discovered by the British Antarctic Expedition (1907–09) under Shackleton, and named for Sir James Mills who, with the government of New Zealand, paid the cost of towing the expedition ship ''Nimrod'' to Antarctica in 1908. Mount Nimrod Mount Nimrod () is a mountain at , standing 6 km SSE of Mount Saunders. It was discovered by the British Anta ...

Mill Glacier
Mill Glacier is a tributary glacier, wide, flowing northwest between the Dominion Range and the Supporters Range into Beardmore Glacier, Antarctica. It was discovered by the British Antarctic Expedition, 1907–09, and named for Hugh Robert Mill, a British geographer and Antarctic historian.

Mountains Of The Ross Dependency
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 and ...
