Granite Harbor
Granite Harbour () is a bay in the coast of Victoria Land, Antarctica, about long, entered between Cape Archer and Cape Roberts. It was discovered and named by the British National Antarctic Expedition (BrNAE) of 1901–04 in the ''Discovery'' in January 1902, while searching for safe winter quarters for the ship. The name derives from the great granite boulders found on its shores. Features Granite Harbor extends from Cape Archer at the south tip of Evans Piedmont Glacier to Cape Roberts on the north of Wilson Piedmont Glacier. Its main inflow is Mackay Glacier, which terminates in Mackay Glacier Tongue, extending into the bay. Features to the north of this glacier include Tiger Island, Benson Glacier, Lion Island, Hunt Glacier, Dreikanter Head, Marston Glacier, Kar Plateau and Point Retreat. Features to the south include Cuff Cape, The Flatiron, Devils Punchbowl, Finger Point, New Glacier, Discovery Bluff, Avalanche Bay, Couloir Cliffs, First View Point and Cape Roberts. P ...

Mackay Glacier
Mackay Glacier () is a large glacier in Victoria Land, descending eastward from the Antarctic Plateau, between the Convoy Range and Clare Range, into the southern part of Granite Harbour. It was discovered by the South magnetic pole party of the British Antarctic Expedition, 1907–09, and named for Alistair Mackay, a member of the party. The glacier's glacier tongue, tongue is called Mackay Glacier Tongue. First mapped by the British Antarctic Expedition, 1910–13 and named for Alistair F. Mackay, a member of the party. Its mouth is south of the Evans Piedmont Glacier and the Mawson Glacier. It is north of the Wilson Piedmont Glacier and the Ferrar Glacier. Course The Mackay Glacier forms on the Antarctic Plateau to the south of Gateway Nunatak and the north of Willett Range. It flows east to the north of Detour Nunatak and Pegtop Mountain, which separate it from Frazier Glacier to the south, which flows past the Clare Range further to the south. It is joined by Frazier Glacier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Antarctic Expedition, 1910–13
The ''Terra Nova'' Expedition, officially the British Antarctic Expedition, was an expedition to Antarctica which took place between 1910 and 1913. Led by Captain Robert Falcon Scott, the expedition had various scientific and geographical objectives. Scott wished to continue the scientific work that he had begun when leading the ''Discovery'' Expedition from 1901 to 1904, and wanted to be the first to reach the geographic South Pole. He and four companions attained the pole on 17 January 1912, where they found that a Norwegian team led by Roald Amundsen had preceded them by 34 days. Scott's party of five died on the return journey from the pole; some of their bodies, journals, and photographs were found by a search party eight months later. The expedition, named after its supply ship, was a private venture financed by public contributions and a government grant. It had further backing from the Admiralty, which released experienced seamen to the expedition, and from the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Victoria Land
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). 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 oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Bays Of The Ross Dependency
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a ''gulf'', ''sea'', ''sound'', or ''bight''. A ''cove'' is a small, circular bay with a narrow entrance. A ''fjord'' is an elongated bay formed by glacial action. The term ''embayment'' is also used for , such as extinct bays or freshwater environments. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore ...

Granite House - Geology Point, Granite Harbour, Antarctica, November 1989
Granite ( ) is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly always m ...
