Colosseum Ridge
Colosseum Ridge () is a ridge between Haskell Ridge and Richardson Hill in the Darwin Mountains. The ridge contains pyramidal peaks and five large cirques, the appearance of the latter bearing a resemblance to the Colosseum The Colosseum ( ; it, Colosseo ) is an oval amphitheatre in the centre of the city of Rome, Italy, just east of the Roman Forum. It is the largest ancient amphitheatre ever built, and is still the largest standing amphitheatre in the world to ... in Rome. It was mapped and named by the Victoria University of Wellington Antarctic Expedition (1962–63).

Ridge
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haskell Ridge
Haskell Ridge () is a rocky ridge west of Colosseum Ridge in the Darwin Mountains of Antarctica. It was mapped by the Victoria University of Wellington Antarctic Expedition The Antarctic Research Centre (ARC) is part of the School of Geography, Environment and Earth Sciences at Victoria University of Wellington. Its mission is to research "Antarctic climate history and processes, and their influence on the global clima ... (1962–63) and named after T.R. Haskell, a member of the expedition.

Cirques
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

Colosseum
The Colosseum ( ; it, Colosseo ) is an oval amphitheatre in the centre of the city of Rome, Italy, just east of the Roman Forum. It is the largest ancient amphitheatre ever built, and is still the largest standing amphitheatre in the world today, despite its age. Construction began under the emperor Vespasian () in 72 and was completed in 80 AD under his successor and heir, Titus (). Further modifications were made during the reign of Domitian (). The three emperors that were patrons of the work are known as the Flavian dynasty, and the amphitheatre was named the Flavian Amphitheatre ( la, Amphitheatrum Flavium; it, Anfiteatro Flavio ) by later classicists and archaeologists for its association with their family name (Flavia (gens), Flavius). The Colosseum is built of travertine#Uses, travertine limestone, tuff (volcanic rock), and brick-faced Roman concrete, concrete. It could hold an estimated 50,000 to 80,000 spectators at various points in its history, having an average a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria University Of Wellington Antarctic Expedition
The Antarctic Research Centre (ARC) is part of the School of Geography, Environment and Earth Sciences at Victoria University of Wellington. Its mission is to research "Antarctic climate history and processes, and their influence on the global climate system. The current director of the Antarctic Research Centre is Associate Professor Robert McKay.
