Sandwich Bluff

	Sandwich Bluff Sandwich Bluff () is a flat-topped mountain, 610 m, broken sharply at its west side by a steep dark bluff standing slightly west of center on Vega Island in the James Ross Island group. Discovered by the Swedish Antarctic Expedition The Swedish Antarctic Expedition of 1901–1903 was a scientific expedition led by Otto Nordenskjöld and Carl Anton Larsen. It was the first Swedish endeavour to Antarctica in the Heroic Age of Antarctic Exploration. Background Otto Nordensk ... under Nordenskjold, 1901–04. Charted in 1945 by the FlDS, and so named because a horizontal snow-holding band of rock breaks the western cliff giving it the appearance of a sandwich when viewed from the north.

picture info	Mountain A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

picture info	Vega Island Vega Island is a small island to the northwest of James Ross Island, on the Antarctic Peninsula. It is separated from James Ross Island by Herbert Sound. The island was named by Otto Nordenskjold, leader of the Swedish Antarctic Expedition (1901–04) in honour of the ship making the first voyage through the Northeast Passage, 1878-79. Vega Island is an important site for paleontology. The region is extremely rich in terrestrial and marine fossils which span the boundary of the Cretaceous and Tertiary periods, covering the point in time when dinosaurs became extinct. Fossils found on the island include hadrosaurs, plesiosaurs, and mosasaurs. Geography The island is a rare volcano type called a móberg, or tuya, which was formed by a three-stage eruption sequence below an ice cap. Stage one was a subglacial hyaloclastic eruption, which shattered the lava into glass, ash, and sand which has since weathered to yellow palagonite layers. The second phase was a lava eruption into a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	James Ross Island Group The James Ross Island group is a group of islands located close to the northeastern tip of the Antarctic Peninsula. The largest islands in the group are James Ross Island, Snow Hill Island, Vega Island, and Seymour Island. The islands lie to the south of the Joinville Island group. The groups contains several scientific bases, notably Marambio Base ("Antarctica's Entrance Door") , motto = , anthem = , pushpin_map = Antarctica , pushpin_map_alt = Location within Antarctica , pushpin_map_caption = Location within Antarctica , ..., and numerous important palaeontological sites.

picture info	Swedish Antarctic Expedition The Swedish Antarctic Expedition of 1901–1903 was a scientific expedition led by Otto Nordenskjöld and Carl Anton Larsen. It was the first Swedish endeavour to Antarctica in the Heroic Age of Antarctic Exploration. Background Otto Nordenskjöld, a Swedish geologist and geographer, organized and led a scientific expedition of the Antarctic Peninsula. The expedition's overall command was placed under the Norwegian Carl Anton Larsen, an experienced Antarctic explorer who served as captain of , and who had previously commanded a whaling reconnaissance mission in 1892–1893. Seven other scientists, including archaeologist Johan Gunnar Andersson, botanist Carl Skottsberg, and zoologist Axel Ohlin, along with 16 officers and men joined them on the voyage. On 16 October 1901, the ''Antarctic'' left the Port of Gothenburg. Events Despite its end and the great hardships endured, the expedition would be considered a scientific success, with the parties having explored muc ...
