Hobbs Glacier (Victoria Land)
Hobbs Ridge () is a prominent arc-shaped ridge which circumscribes Hobbs Glacier to the north and northwest and forms the divide with the lower part of Blue Glacier, on the Scott Coast of Victoria Land, Antarctica. It was named in association with Hobbs Glacier. It forms the northernmost part of the Denton Hills. Location Hobbs Ridge, which includes Hobbs Peak, Goat Mountain, Mount Kowalczyk and Williams Peak, lies to the southeast of the mouth of Blue Glacier, and surrounds the north and east of Hobbs Glacier. The Hobbs Stream leads from Hobbs Glacier into Salmon Bay, just north of Cape Chocolate. Features Features include: Davison Peak A coastal peak, high, located east of Hobbs Peak. Named after William Davison, Zoology Department, Canterbury University, who from 1983 specialized in Antarctic fish research. Hobbs Peak . A prominent peak, high, on the divide between the Hobbs and Blue Glaciers. It is the highest point on the E-W section of this dividing ridge. Clim ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

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 78th parallel south, 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 Victoria of the United Kingdom, 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. History Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 Meteorite, meteorites in Antarctica, some of which were found near the Allan Hills in Victoria Land. The meteorites appeared to have undergone little change since they were formed at what scientists believe was the birth of the Solar System. In 1981, Lichen, lichens fo ...

Blue Glacier (Antarctica)
Blue Glacier () is a large glacier which flows into Bowers Piedmont Glacier about south of New Harbour, in Victoria Land, Antarctica. It was discovered by the British National Antarctic Expedition (BrNAE) under Robert Falcon Scott, 1901–04, who gave it this name because of its clear blue ice at the time of discovery. Location Blue Glacier rises to the north of Armitage Saddle, and flows north. The coastal range that borders the lower Koettlitz Glacier and the McMurdo Ice Shelf lies to the east, and the Royal Society Range is to the west. In its lower section the Blue Glacier turns to the east and joins the Bowers Piedmont Glacier on the west coast of the McMurdo Sound. Left tributary glaciers Glaciers entering from the left (west) flowing from the Royal Society Range, include (from south to north) Salient, Hooker, Mitchell, Spring, Covert, Amos Glacier and Geoid Glacier.

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 The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface. It is called the True South Pole to distinguish .... 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.

Denton Hills
The Denton Hills () are a group of rugged foothills, long southwest–northeast and wide, to the east of the Royal Society Range on the Scott Coast, Victoria Land, Antarctica. The Denton Hills comprise a series of eastward-trending ridges and valleys circumscribed by Howchin Glacier, Armitage Saddle, Blue Glacier, the coast, and Walcott Bay. The highest summits, Mount Kowalczyk at , and Goat Mountain at , rise from Hobbs Ridge in the northern part of the foothills. Elevations decrease southward as in Kahiwi Maihao Ridge, high near the center of the group and the Xanadu Hills, high at the southern end. The principal glaciers (Hobbs, Blackwelder, Salmon, Garwood, Joyce, Rivard, Miers, Adams, Ward) flow east but have receded, leaving several dry valleys. Exploration The Denton Hills were discovered and roughly mapped by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott. The hills were mapped in detail by United States Antarctic Research ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Glacier
Blue Glacier is a large glacier located to the north of Mount Olympus in the Olympic Mountains of Washington. The glacier covers an area of and contains of ice and snow in spite of its low terminus elevation. The glacier length has decreased from about in 1800 to in the year 2000. Just in the period from 1995 and 2006, Blue Glacier retreated . Blue Glacier is also thinning as it retreats and between 1987 and 2009 the glacier lost of its depth near its terminus and between in the uppermost sections of the glacier known as the accumulation zone. Description Starting at an elevation of near Mount Olympus's three summits, the Blue Glacier begins as a snow/ice field separated by arêtes.Google Earth elevation for GNIS coordinates. As the glacier flows north, it cascades down a steep slope and thus, the smooth ice turns into a chaotic icefall, replete with seracs and crevasses. After the ice passes the icefall, the glacier ends up in a valley and takes a left turn to the west. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Chocolate
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. Naming and exploration Koettlitz Glacier was discovered by the British National Antarctic Expedition (1901–04) which named it for Dr. Reginald Koettlitz, physician and botanist of the expedition. Glaciology The Koettlitz Glacier appears to have been smaller during the Last Glacial Maximum (LGM) than it is today, while the Ross Ice Shelf was larger. There is evidence that during the LGM the mouth of the Pyramid Trough was blocked by grounded Ross Sea ice until at least 11,000 years ago. In the last 3,000 years the glacier has advanced, and today the mouth of ice-free Pyramid Trough is blocked by the Koettlitz Glacier. Under this hypothesis, the glacier may have been thicker at the coast due to buttressing, but may have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridges Of Victoria Land
A ridge is a long, narrow, elevated geomorphologic landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest, with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline. Limitations on the dimensions of a ridge are lacking. Its height above the surrounding terrain can vary from less than a meter to hundreds of meters. A ridge can be either depositional, erosional, tectonic, or a combination of these in origin and can consist of either bedrock, loose sediment, lava, or ice depending on its origin. A ridge can occur as either an isolated, independent feature or part of a larger geomorphological and/or structural feature. Frequently, a ridge can be further subdivided into smaller geomorphic or structural elements. Classification As in the case of landforms in general, there is a lack of any commonly agreed classi ...
