McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999. The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross ...
[note 1] West Antarctica is covered by the West Antarctic Ice Sheet. There has been some concern about this ice sheet, as there is a small chance it will collapse due to rising temperatures in the region. If it does, global ocean levels will rise by a few metres in a short period of time. [citation needed]
The South Pole Traverse, also called the South Pole Overland Traverse (SPoT), [2] or McMurdo–South Pole Highway [3] is an approximately 995-mile-long (1,601 km) flagged route over compacted snow and ice [4] in Antarctica that links McMurdo Station on the coast to the Amundsen–Scott South Pole Station, both operated by the National Science Foundation of the United States.

McMurdo Sound, Antarctica Weddell seal underwater in McMurdo Sound. The McMurdo Sound is a sound in Antarctica, known as the southernmost passable body of water in the world, located approximately 1,300 kilometres (810 mi) from the South Pole. [1]
Mount Erebus (/ ˈ ɛr ɪ b ə s /) is the southernmost active volcano on Earth, located on Ross Island in the Ross Dependency in Antarctica.With a summit elevation of 3,792 metres (12,441 ft), it is the second most prominent mountain in Antarctica (after Mount Vinson) and the second-highest volcano in Antarctica (after the dormant Mount Sidley).
They are south of the Kukri Hills, southeast of the Quartermain Mountains, and northeast of the Worcester Range. With its summit at 4,025 metres (13,205 ft), the massive Mount Lister forms the highest point in this range. Mount Lister is located along the western shore of McMurdo Sound between the Koettlitz, Skelton and Ferrar glaciers.
The McMurdo Volcanic Group is a large group of Cenozoic volcanic rocks in the western Ross Sea and central Transantarctic Mountains areas of Antarctica. [1] It is one of the largest provinces of alkaline volcanism in the world, having formed as a result of continental rifting along the West Antarctic Rift System.
Map showing location of Taylor Valley Taylor Valley in center of west of map, opposite Ross Island. Taylor Valley is one of the McMurdo Dry Valleys.Parts of the area were visited by British expeditions led by Captain Robert Falcon Scott (1901–04 and 1910–13), who referred to Taylor Valley, as well as Beacon Valley and Pyramid Trough (named later), as "dry valleys."
