The Beardmore Glacier in Antarctica is one of the largest valley glaciers in the world, being 200 km (125 mi) long and having a width of 40 km (25 mi). [1] It descends about 2,200 m (7,200 ft) [1] from the Antarctic Plateau to the Ross Ice Shelf and is bordered by the Commonwealth Range of the Queen Maud Mountains on the eastern side and the Queen Alexandra Range of the Central Transantarctic ...
Mount Kirkpatrick holds one of the most important fossil sites in Antarctica, the Hanson Formation. Because Antarctica used to be warmer and supported dense conifer and cycad forest, and because all the continents were fused into a giant supercontinent called Pangaea , many ancient Antarctic wildlife share relatives elsewhere in the world.
The Hanson Formation (also known as the Shafer Peak Formation) is a geologic formation on Mount Kirkpatrick and north Victoria Land, Ross Dependency, Antarctica.It is one of the two major dinosaur-bearing rock groups found on Antarctica to date; the other is the Snow Hill Island Formation and related formations from the Late Cretaceous of the Antarctic Peninsula.
Expeditions in Antarctica before the Heroic Age of Antarctic Exploration, 1897 1780s to 1839 – American and British whalers and sealers make incidental discoveries. 1819 – William Smith discovers South Shetland Islands ( 62°00′S 58°00′W / 62.000°S 58.000°W / -62.000; -58.000 ), the first land discovered south of 60 ...

Map of the Mount Kirkpatrick fossil location in Antarctica where Glacialisaurus was found (C). Fossils of a sauropodomorph dinosaur were discovered by a field team from Augustana College led by paleontologist William R. Hammer during 1990–91 fieldwork in the lower Hanson Formation of Mount Kirkpatrick in the Central Transantarctic Mountains of Antarctica, dating to the Early Jurassic.
The Main Base Hut of the Australasian Antarctic Expedition. The Australasian Antarctic Expedition took place between 1911–1914 and was led by Sir Douglas Mawson. It concentrated on the stretch of Antarctic coastline between Cape Adare and Mount Gauss, carrying out mapping and survey work on coastal and inland territories.
Fossils of trilobites and Marocella mira and Dailyatia have been found in the formation, named after Ernest Shackleton, who led a failed expedition into Antarctica. At time of deposition, the Antarctic Plate has been established to be just south of the equator as part of the supercontinent Pannotia , contrasting with its present position at 82 ...
