Wright Peak, Antarctica
The Jones Mountains are an isolated group of mountains, trending generally east–west for 43 km (27 mi), situated on the Eights Coast, Ellsworth Land, about 80 km (50 mi) south of Dustin Island in Antarctica. The charts of the USAS, 1939–41, show mountains in this approximate location and relationship to Dustin and Thurston Islands, indicating they were sighted in the flight from the ship ''Bear'', February 27, 1940. The mountains appear in distant air photos taken by US Navy Operation Highjump, December 30, 1946, and were observed from USN aircraft by Edward Thiel and J. Campbell Craddock, January 22, 1960. The naming was proposed by Thiel and Craddock after Dr. Thomas O. Jones (1908–93), American chemist; senior NSF official in charge of the U.S. Antarctic Research Program, 1958–78; Director, Division of Environmental Science, NSF, 1965–69; Deputy Assistant Director for National and International Programs, NSF, 1969–78.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern 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 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 measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Ellsworth Land
Ellsworth Land is a portion of the Antarctic continent bounded on the west by Marie Byrd Land, on the north by Bellingshausen Sea, on the northeast by the base of Antarctic Peninsula, and on the east by the western margin of the Filchner–Ronne Ice Shelf. It extends between 103°24'W and 79°45'W. The area west of 90°W is unclaimed, the area between 84°W and 90°W is claimed by Chile only, and the remainder by Chile and the United Kingdom as a part of the British Antarctic Territory. Eights Coast stretches between 103°24'W and 89°35'W, and Bryan Coast between 89°35'W and 79°45'W. It is largely a high ice plateau, but includes the Ellsworth Mountains and a number of scattered mountain groups: Hudson, Jones, Behrendt, Hauberg, Merrick, Sweeney and Scaife Mountains. This land lies near the center of the area traversed by American explorer Lincoln Ellsworth on an airplane flight during November–December 1935. It was named for him by the Advisory Committee on Antarct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dustin Island
Dustin Island is an island about long, lying southeast of Cape Annawan, Thurston Island. The feature forms the SE limit of Seraph Bay. It was discovered by Rear Admiral Byrd and other members of the USAS in a flight from the ''Bear'' on February 27, 1940. It was named by Byrd for Frederick G.

Thurston Island
Thurston Island is an ice-covered, glacially dissected island, long, wide and in area, lying a short way off the northwest end of Ellsworth Land, Antarctica. It is the third-largest island of Antarctica, after Alexander Island and Berkner Island. The island was discovered from the air by Rear Admiral Byrd on February 27, 1940, who named it for W. Harris Thurston, a New York textile manufacturer, designer of the windproof "Byrd Cloth" and sponsor of Antarctic expeditions. Thurston Island is separated from the mainland by Peacock Sound, which is occupied by the western portion of Abbot Ice Shelf. It divides Bellingshausen Sea to the east from Amundsen Sea to the west. Originally mistaken as a peninsula, the feature was not recognised an island until 1960. Geography The western extremity of the island is Cape Flying Fish. The eastern extremity is Cape Annawan, off Tierney Peninsula. The southeast end of the island is Cape Walker. The island is divided south-north by the ...

Operation Highjump
Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV. The operation was organized by Rear Admiral Richard E. Byrd, Jr., USN (Ret), Officer in Charge, Task Force 68, and led by Rear Admiral Ethan Erik Larson, USN, Commanding Officer, Task Force 68. Operation HIGHJUMP commenced 26 August 1946 and ended in late February 1947. Task Force 68 included 4,700 men, 13 ships, and 33 aircraft. HIGHJUMP's objectives, according to the U.S. Navy report of the operation, were: # Training personnel and testing equipment in frigid conditions; # Consolidating and extending the United States' sovereignty over the largest practicable area of the Antarctic continent (publicly denied as a goal before the expedition ended); # Determining the feasibility of establishing, maintaining, and utilizing bases in the Antarctic an ...

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing. The NSF's director and deputy director are appointed by the President of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while t ...

Christmas Day
Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is preceded by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night. Christmas Day is a public holiday in many countries, is celebrated religiously by a majority of Christians, as well as culturally by many non-Christians, and forms an integral part of the holiday season organized around it. The traditional Christmas narrative recounted in the New Testament, known as the Nativity of Jesus, says that Jesus was born in Bethlehem, in accordance with messianic prophecies. When Joseph and Mary arrived in the city, the inn had no room and so they were offered a stable where the Christ Child was soon born, with angels proclaim ...
