Peneplain Peak
Peneplain Peak () is a peak (2,650 m) located midway along Hampton Ridge, which lies between Montgomerie Glacier and Mackellar Glacier in Queen Alexandra Range The Queen Alexandra Range is a major mountain range of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica. It is about long, bordering the entire western side of Beardmore Glacier from the Polar Plateau .... So named by the Ohio State University Geological Party, 1967–68, because an excellent exposure of the " Kukri Peneplain," an ancient erosion surface, is present on the peak.

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 Hill ...

Hampton Ridge
Hampton Ridge is a ridge about long in the Queen Alexandra Range of Antarctica, running north from Pagoda Peak between Montgomerie Glacier and Mackellar Glacier. It was named by the Advisory Committee on Antarctic Names for Major William C. Hampton, commanding officer of the U.S. Army Aviation Detachment which supported the Texas Tech Shackleton Glacier Expedition The Texas Tech Shackleton Glacier Expedition took place first from 1962/63 and then again from 1964/65. The expedition, led by F. Alton Wade, was sponsored by Texas Technological College (now Texas Tech University). It explored areas of Antarctica. ..., 1964–65.

Montgomerie Glacier
Montgomerie Glacier () is a narrow tributary glacier, long, flowing north along the west side of Hampton Ridge in the Queen Alexandra Range of Antarctica to enter Lennox-King Glacier. It was named by the Northern Party of the New Zealand Geological Survey Antarctic Expedition of 1961–62 for John Montgomerie Colonel John Montgomerie (died 1731) was colonial governor of New York and New Jersey from 1728 to 1731. Life Montgomerie was born in the parish of Beith in Scotland. His father, Francis Montgomerie, was a member of the Privy Council under ..., assistant surveyor of that party.

Mackellar Glacier
Lennox-King Glacier is a large valley glacier, about long, draining Bowden Névé and flowing northeast between the Holland Range and the Queen Alexandra Range of Antarctica to enter Richards Inlet, Ross Ice Shelf. It was named by the New Zealand Geological Survey Antarctic Expedition (1959–60) for Lieutenant Commander James Lennox-King, Royal New Zealand Navy, leader at Scott Base Scott Base is a New Zealand Antarctic research station at Pram Point on Ross Island near Mount Erebus in New Zealand's Ross Dependency territorial claim.

Queen Alexandra Range
The Queen Alexandra Range is a major mountain range of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica. It is about long, bordering the entire western side of Beardmore Glacier from the Polar Plateau to the Ross Ice Shelf. Alternate names for this range include Alexandra Mountains, Alexandra Range and Königin Alexandra Gebirge. The highest peak of the range is Mount Kirkpatrick at . Other peaks in the range include Mount Dickerson (4,120 m). Discovery This mountain range was discovered on the journey toward the South Pole by the British Antarctic Expedition, and was named by Ernest Shackleton for Queen consort Alexandra of the United Kingdom. Shackleton and his men, and a later expedition headed by Robert Falcon Scott, both collected rock samples from the range that contained fossils. The discovery that multicellular life forms had lived so close to the South Pole was an additional piece of evidence that accompanied the publica ...

Kukri Peneplain
The Kukri Peneplain is a near-horizontal and flat unconformity in the Transantarctic Mountains. The peneplain formed by erosion of the granitic and metamorphic basement rocks during the Paleozoic (Silurian to Devonian The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, w ...). Kukri Peneplain dips gently to the west.

Erosion Surface
In geology and geomorphology, an erosion surface is a surface of rock or regolith that was formed by erosion and not by construction (e.g. lava flows, sediment deposition) nor fault displacement. Erosional surfaces within the stratigraphic record are known as unconformities, but not all unconformities are buried erosion surfaces. Erosion surfaces vary in scale and can be formed on a mountain range or a rock. Particularly large and flat erosion surfaces receive the names of peneplain, paleoplain, planation surface or pediplain. An example of erosion surface is road surface erosion which is caused by natural and anthropogenic factors. Erosion surface can be measured through direct, contact measurement methods and indirect, non-contact measurement methods. Road surface erosion Just like mountains and rocks, erosion can also occur on unsealed roads due to natural and anthropogenic factors. Road surface erosion could be caused by snowfall, rainfall and wind. The material an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 a ...
