Walton Mountains
Walton Mountains is an isolated chain of three predominantly snow-covered mountain masses, rising to about 1,450 m at Mount McArthur, extending south from Schubert Inlet for 25 miles (40 km) in central Alexander Island, Antarctica. The mountains were first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. Resighted from the air by the United States Antarctic Service in 1940, and in 1947 by the Ronne Antarctic Research Expedition under Ronne. Ronne named the mountains after Lieutenant Colonel R.C. Walton, United States Marine Corps, of the Office of Naval Research, who was instrumental in obtaining the loan of a ship from the Navy and in securing Navy assistance for the Ronne expedition.

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

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 area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are inselberg, 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, ecosystems of mountains: different elevations hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schubert Inlet
Schubert Inlet () is an ice-filled inlet in Antarctica. Description Schubert Inlet is long and wide, indenting the west coast of Alexander Island, lying between the Colbert Mountains north of the inlet and the Walton Mountains south of the inlet. The inlet receives ice flowing into it throughout the whole year, mainly because the inlet is adjacent to the Wilkins Ice Shelf, which lies immediately west. The inlet was first mapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. It was named by the United Kingdom Antarctic Place-Names Committee for Franz Schubert (1797–1828), Austrian composer.

Lincoln Ellsworth
Lincoln Ellsworth (May 12, 1880 – May 26, 1951) was an American polar explorer, engineer, surveyor, and author. He led the first Arctic and Antarctic air crossings. Early life Linn Ellsworth was born in Chicago, Illinois on May 12, 1880. His parents were Eva Frances (née Butler) and James Ellsworth, a wealthy coal mine owner and financier.http://pabook2.libraries.psu.edu/palitmap/bios/Ellsworth__Lincoln.html He was named Linn after his uncle William Linn, but changed his name to Lincoln when he was a child. His mother died in 1888. Ellsworth and his sister moved to Hudson, Ohio to live with his grandmother. He attended the Western Reserve Academy in Hudson and The Hill School in Pottstown, Pennsylvania. He took two years longer than usual to graduate, before entering the Sheffield Scientific School at Yale University. His academic performance was poor, and he subsequently enrolled at Columbia University School of Mines and studied civil engineering. He joined the frat ...

Ronne Antarctic Research Expedition
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica. Background Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife.

Havre Mountains
The Havre Mountains () are a large group of mountains forming the northwestern extremity of Alexander Island, Antarctica, extending in an east–west direction between Cape Vostok and the Russian Gap. They were first seen in 1821 by a Russian expedition under Fabian Gottlieb von Bellingshausen and re-sighted by the Belgian Antarctic Expedition, 1897–99. They were roughly charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, who named them for Le Havre, the French port from which the ''Pourquoi-Pas (1908), Pourquol Pas?'' sailed in 1908. The mountains were mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960.

Lassus Mountains
The Lassus Mountains () are a large group of mountains, long and wide, rising to and extending south from Palestrina Glacier in the northwest part of Alexander Island, Antarctica. They overlook Lazarev Bay and a few minor islands within the bay such as Dint Island and Umber Island; Haydn Inlet lies to the south while the Havre Mountains lie immediately north. The mountains were probably first seen on 9 January 1821 by a Russian expedition under Fabian Gottlieb von Bellingshausen. They were photographed from the air in 1936 by the British Graham Land Expedition but mapped as part of the Havre Mountains. They were first mapped in detail, from air photos taken by the Ronne Antarctic Research Expedition (1947–48), by D. Searle of the Falkland Islands Dependencies Survey in 1960, and were named by the UK Antarctic Place-Names Committee after Orlandus Lassus, a Belgian composer of the 16th century.
