Johnson Spur
Johnson Spur () is a rocky spur located south-southeast of Taylor Spur, southwest of Batil Spur and north-northwest of Long Peak, on the east side of the Sentinel Range in the Ellsworth Mountains of Antarctica. It forms the southeastern extremity of the Doyran Heights, and overlooks Rutford Ice Stream to the east and Obelya Glacier to the west. The feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for William F. Johnson, a meteorologist at South Pole Station South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west.

Batil Spur
Batil Spur ( bg, text=Батилов рид, italic=no, ‘Batilov Rid’ \ba-'ti-lov 'rid\) is the rocky ridge extending 3.9 km and 1.3 km wide, forming the southeast extremity of Flowers Hills on the east side of Sentinel Range in Ellsworth Mountains. It surmounts Rutford Ice Stream to the east and the ends of its tributaries flowing from Sikera Valley and Doyran Heights to the west.

Long Peak
Long Peak () is a bare rock peak, high, on the extended ridge line, east-northeast of Mount Landolt in the Petvar Heights of the southeast Sentinel Range in the Ellsworth Mountains of Antarctica. It overlooks the lower courses of Drama Glacier to the north and Gabare Glacier to the south. The peak was mapped by the United States Geological Survey from surveys and U.S. Navy aerial photographs from 1957 to 1959, and was named by the Advisory Committee on Antarctic Names in 1984 after James W.

Sentinel Range
The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about and is 24 to 48 km (15 to 30 mi) wide. Many peaks rise over and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.Sentinel Range. SCAR Composite Antarctic Gazetteer. Sentinel Range comprises a main ridge (featuring Vinson Massif in its southern portion) and a number of distinct heights, ridges and mountains on its east side, including (south to north) , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellsworth Mountains
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a long and wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson () constituting the highest point on the continent.Bockheim, J.G., Schaefer, C.E., 2015. ''Soils of Ellsworth Land, the Ellsworth Mountains''. In: Bockheim, J.G. (Ed.), ''The Soils of Antarctica. World Soils Book Series'', Springer, Switzerland, pp. 169–181. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones. Discovery The mountains were discovered on November 23, 1935, by Lincoln Ellsworth in the course of a trans-Antarctic flight from Dundee Island to the Ross Ice Shelf. He gave them the descriptive name Sentinel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Rutford Ice Stream
Rutford Ice Stream () is a major Antarctic ice stream, about long and over wide, which drains southeastward between the Sentinel Range, Ellsworth Mountains and Fletcher Ice Rise into the southwest part of Ronne Ice Shelf. Named by US-ACAN for geologist Robert Hoxie Rutford, a member of several USARP expeditions to Antarctica; leader of the University of Minnesota Ellsworth Mountains Party, 1963-1964. Rutford served as Director of the Division of Polar Programs, National Science Foundation, 1975-1977. The ice stream is situated in a deep trough which is a tectonic feature between the Ellsworth Mountains and the Fletcher Promontory. Because of this the ice stream position may have been stable for millions of years. The bed of the ice stream reaches below sea level. Therefore, between the bed of the ice stream and the height of the Ellsworth Mountains there is a vertical relief of over a distance of only . At the upper (inland) end of the ice stream the ice thickness reache ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obelya Glacier
Obelya Glacier ( bg, ледник Обеля, lednik Obelya, ) is the long and wide glacier on the east side of southern Sentinel Range in Ellsworth Mountains, Antarctica, situated south of Remington Glacier, and flowing southeastwards along the southwest side of Johnson Spur and east of Mount Benson to join Thomas Glacier. The glacier is named after the settlement of Obelya in Western Bulgaria, now part of the city of Sofia. Location Obelya Glacier is centred at . US mapping in 1961, updated in 1988.

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...
