The Stage (Antarctica)
The Stage is a prominent moraine floored amphitheater (a cirque) between West Aisle Ridge and Central Aisle Ridge on the north side of Renegar Glacier, Scott Coast. The cirque floor, at , is relatively flat. The feature was visited by D. N. B. Skinner, D. N. B. Skinner's New Zealand Geological Survey field party, 1977–78, which suggested the name; viewed from the lower Renegar Glacier the elevated floor of the amphitheater appears to be the ideal stage for some great theater.

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Cirque
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 ...

Central Aisle Ridge
Central Aisle Ridge () is a north–south ridge immediately east of The Stage on the north side of lower Renegar Glacier, Scott Coast. The name is derived from the position of the ridge relative to West Aisle Ridge, East Aisle Ridge, and its proximity to The Stage. It was named by the New Zealand Geographic Board (1994) following work by a New Zealand Geological Survey GNS Science ( mi, Te Pū Ao), officially registered as the Institute of Geological and Nuclear Sciences Limited, is a New Zealand Crown Research Institute.

Renegar Glacier
Koettlitz Glacier is a large Antarctic glacier lying west of Mount Morning and Mount Discovery in the Royal Society Range, flowing from the vicinity of Mount Cocks northeastward between Brown Peninsula and the mainland into the ice shelf of McMurdo Sound. It was discovered by the British National Antarctic Expedition (1901–04) which named it for Dr. Reginald Koettlitz, physician and botanist of the expedition.

This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice.

Scott Coast
Scott Coast () is the portion of the coast of Victoria Land, Antarctica between Cape Washington and Minna Bluff. It was named by the New Zealand Antarctic Place-Names Committee in 1961 after Captain Robert Falcon Scott, Royal Navy, leader of the ''Discovery'' Expedition (1901–1904) and the British Antarctic Expedition (1910-1913), who died on the return journey from the South Pole. Much of the early exploration of this coastline was accomplished by Scott and his colleagues, and many of the names in the region were bestowed by him.

Landforms Of Victoria Land
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
