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 ...

Harris Valley
Harris Valley () is a valley just east of Coxcomb Peak in the Allan Hills of Victoria Land, Antarctica. It was reconnoitered by the New Zealand Antarctic Research Program Allan Hills Expedition (1964), who gave the name after Professor T.M. Harris who has made outstanding contributions to Mesozoic paleobotany Paleobotany, which is also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeogr ....

Shipton Ridge
Shipton Ridge () is the main ridge forming the northeastern arm of the Allan Hills in Victoria Land. Reconnoitered by the New Zealand Antarctic Research Program (NZARP) Allan Hills Expedition, 1964. They named it after Eric Shipton Eric Earle Shipton, CBE (1 August 1907 – 28 March 1977), was an English Himalayan mountaineer. Early years Shipton was born in Ceylon (now Sri Lanka) in 1907 where his father, a tea planter, died before he was three years old. When he was eigh ..., Himalayan mountaineer, because of his association with Professor N.E. Odell, for whom the adjacent Odell Glacier is named.

Allan Hills
The Allan Hills are a group of hills at the end of the Transantarctic Mountains System, located in Oates Land and Victoria Land regions of Antarctica. They are mainly ice free and about long, lying just north-west of the Coombs Hills near the heads of Mawson Glacier and Mackay Glacier. They were mapped by the New Zealand party (1957–58) of the Commonwealth Trans-Antarctic Expedition and named for Professor R. S. Allan of the University of Canterbury, New Zealand. Allan Hills is referred to as the ''Allan Nunatak'', and mapped north of Carapace Nunatak, in the memoirs of the Scott Base Leader Adrian Hayter. Both names are in the USGS listing. Meteorites According to William A. Cassidy, describing the 1976–1977 ANSMET meteorite collecting season, "Looking across the Mackay Glacier at the great sky-blue patches of ice beyond Mount Brooke, we were looking for the first time at ice that had a tremendous upstream collecting area. We were looking at Meteorite Heaven... Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oates Land
Oates Land is a region of Antarctica. It is variously defined as a portion of the East Antarctica near the coast stretching along and inland from the Oates Coast (see map) and as an officially delineated wedge-shaped segment of the Australian Antarctic Territory. The segment of the Australian claim extends between 153°45' E and 160° E, forming a wedge between Latitude 60° S and the South Pole. It is bounded in the east by the Ross Dependency and overlaps George V Land to the west. Exploration Oates Land was discovered in February 1911 by Lieutenant Harry Pennell of the Royal Navy, commander of the '' Terra Nova'', the expedition ship of the British Antarctic Expedition, 1910–13. It is named after Captain Lawrence Edward Grace "Titus" Oates of the 6th (Iniskilling) Dragoons, who, with Captain Robert Falcon Scott and three companions, lost his life on the return journey from the South Pole in 1912.Geographic Names Information System,Oates Land, United States Geological Surv ...

Buttes Of Antarctica
__NOTOC__ In geomorphology, a butte () is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word ''butte'' comes from a French word meaning knoll (but of any size); its use is prevalent in the Western United States, including the southwest where ''mesa'' (Spanish for "table") is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height. Formation Buttes form by weathering and erosion when hard caprock overlies a layer of less resistant rock that is eventually worn away. The harder rock on top of the butte resists erosion. The caprock provides protection for the less resistant rock below from wind abrasion which leaves it standin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
