Pemmican Step
Pemmican Step () is a step-like rise in the level of Tucker Glacier above its junction with Leander Glacier, in Victoria Land. It is very crevassed in its southern half, but there is easy traveling over it toward its north end. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58. It is the second of the steps on this glacier A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight.

Tucker Glacier
Tucker Glacier is a major valley glacier of Victoria Land, about 144 km (90 mi) long, flowing southeast between Admiralty Mountains and Victory Mountains to the Ross Sea. There is a snow saddle at the glacier's head, just west of Homerun Range, from which Ebbe Glacier flows northwestward. The Biscuit Step allows good access near its junction with Trafalgar Glacier. Explored by NZGSAE, 1957–58, and named by them after Tucker Inlet, the ice-filled coastal indentation at the mouth of this glacier named by Captain James Clark Ross in 1841.

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. ... * Pemmican Step References Admiralty Mountains Glaciers of Victoria Land Borchgrevink Coast {{BorchgrevinkCoast-geo-stub ...

Leander Glacier
Leander Glacier () is a tributary glacier in the Admiralty Mountains of Antarctica, draining the area west of Mount Black Prince and flowing south between Shadow Bluff and the McGregor Range to enter Tucker Glacier. It was partially surveyed by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1957–58, which also observed the upper parts of the glacier from Mount Midnight and Mount Shadow. It was named by the NZGSAE for the light cruiser HMNZS ''Leander'' which served in World War II.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites A meteorite is a solid piece of debris from an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand Geological Survey Antarctic Expedition
The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active throughout the 1950s and 1960s.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Slopes Of Antarctica
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, plateau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
