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 Brown Valley is a rectangular ice-covered valley between Mount Kauffman and Mount Kosciusko in the northeast end of the Ames Range, Marie Byrd Land.

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 ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanoes Of Marie Byrd Land
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic ...
