Benes Peak
Usas Escarpment () is an expansive but discontinuous north-facing escarpment in Marie Byrd Land, Antarctica. It is about long, extending roughly west to east along the 76th parallel south from where the elevation of the snow surface descends toward the Ruppert Coast and Hobbs Coast. The position of the escarpment coincides with the north slopes of the Flood Range, Ames Range, McCuddin Mountains, and the eastern peaks of Mount Galla, Mount Aldaz and Benes Peak. The escarpment was observed by members of the United States Antarctic Service The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ..., 1939–41, and in ensuing scientific reports was referred to as 76th Parallel Escarpment.

Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of (including Eights Coast, immediately east of Marie Byrd Land). In 1939, United States President Frankl ...

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] |
Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. The terms ''scarp'' and ''scarp face'' are often used interchangeably with ''escarpment''. Some sources differentiate the two terms, with ''escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ruppert Coast
Ruppert Coast () is that portion of the coast of Marie Byrd Land, Antarctica, between Brennan Point and Cape Burks, or between Saunders Coast in the west and Hobbs Coast in the east. It stretches from 146°31'W to 136°50'W. It was named by R. Admiral Richard Byrd for Col. Jacob Ruppert of New York, a supporter of the second Byrd Antarctic Expedition (1933–1935) that made the first aerial reconnaissance flight along this coast. The United States Geological Survey (USGS) completely mapped the coast from ground surveys and U.S. Navy air photos, 1959–1965.

Hobbs Coast
Hobbs Coast () is that portion of the coast of Marie Byrd Land, Antarctica extending from Cape Burks to a point on the coast opposite eastern Dean Island, at , or between the Ruppert Coast in the west and the Bakutis Coast in the east. It stretches from 136°50′W to 127°35′. The coast was discovered by the US Antarctic Service (1939–1941) and named for Professor William H. Hobbs of the University of Michigan, a glaciologist specializing in polar geography and history. The United States Geological Survey completely mapped the coast from ground surveys and U.S. Navy The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States.

Flood Range
The Flood Range () is an Antarctic range of large snow-covered mountains extending in an E-W direction for about 96 km (60 mi) and forming a right angle with the southern end of the Ames Range in Marie Byrd Land. Discovered by the Byrd Antarctic Expedition in 1934 from a great distance. Reconnaissance flights by the USAS (1939–41) explored the range. The principle mountain was named "Mount Hal Flood" by Byrd for his uncle, the Hon. Henry D. Flood, U.S. Representative from Virginia. The name was subsequently transferred by US-SCAN from the mountain to the entire range. Mount Hal Flood is now known officially as Mount Berlin. Other mountains in this range include Mount Moulton and Mount Bursey. The Flood Range consists of a linear volcanic chain of peaks in which there have been systematic migrations of felsic activity. This activity has moved 90 km from east to west between 9 million and 2.5 million years ago, and 154 km northward from the south end of the Ames Rang ...

Ames Range
The Ames Range is an Antarctic range of snow-covered, flat-topped, steep-sided mountains, extending in a N-S direction for 32 km (20 mi) and forming a right angle with the eastern end of the Flood Range in Marie Byrd Land. They were discovered by the United States Antarctic Service Expedition (1939–41) and named by Richard E. Byrd for his father-in-law, Joseph Ames. The Ames Range consists of three coalescing shield volcanoes: Mount Andrus, Mount Kosciusko and Mount Kauffman, and Mount Boennighausen. Other Features There are several glaciers draining from the Ames Range: * Coleman Glacier * Jacoby Glacier * Rosenberg Glacier Other features include: * Brown Valley * Gardiner Ridge, connecting Mt. Kosciusko to Mt. Kauffman *Lind Ridge * Forrest Pass Forrest Pass () is a broad ice-filled pass between Mount Bursey, in the Flood Range, and the southern elevations of the Ames Range in Marie Byrd Land, Antarctica.

McCuddin Mountains
The McCuddin Mountains are a small cluster of mountains in Antarctica consisting mainly of two large mountains, Mount Flint and Mount Petras, along with several scattered peaks and nunataks. Located in Marie Byrd Land, east of the Ames Range, with Wallace Rock as its southeast extremity. The mountains were discovered and photographed from the air in a flight from West Base of the U.S. Antarctic Service on Dec. 14, 1940. They were mapped by U.S. Geological Survey (USGS) from surveys and U.S. Navy air photos, 1959-65. Named by Advisory Committee on Antarctic Names (US-ACAN) for Rear Admiral Leo B. McCuddin, U.S. Navy (USN), Commander of the U.S. Naval Support Force, Antarctica, 1972. Mount Flint Mount Flint () is a prominent rounded and mainly snow-covered mountain, , standing NW of Mount Petras. The feature was observed from aircraft of the U.S. Antarctic Service (USAS) in Flight G, Dec. 15, 1940, and was briefly referred to as "Mount Gray". Asher Peak is a peak in th ...
