Shell Glacier
Shell Glacier () is a western lobe of the Mount Bird icecap. It descends steeply in the valley north of Trachyte Hill and Harrison Bluff in the center of the ice-free area on the lower western slopes of Mount Bird, Ross Island. Mapped and so named by the New Zealand Geological Survey Antarctic Expedition The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica. The expeditions were notably active throughout the 1950s and 1960s. Features named by the expeditions 1957 ... (NZGSAE), 1958–59, because of the marine shell content of the moraines.

Mount Bird
Mount Bird is a high shield volcano standing about south of Cape Bird, the northern extremity of Ross Island. It was mapped by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott, and apparently named by them after Cape Bird. Endeavour Piedmont Glacier lies on its slopes. There are several western lobes of the Mount Bird icecap. One of these is Quaternary Icefall, which descends steeply into Wohlschlag Bay 1 mile (1.6 km) south of Cinder Hill. The site was mapped and so named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, because of the Quaternary glacial period marine shells carried by the glacier and deposited in terminal moraines. Another such lobe is Shell Glacier. See also *List of volcanoes in Antarctica This is a list of volcanoes in Antarctica. Table A 2017 study claimed to have found 138 volcanoes, of which 91 were previously unknown. Some volcanoes are entirely under the ice sheet. Unconfirmed volc ...

Valley
A valley is an elongated low area often running between Hill, hills or Mountain, mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacier, glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glaciation, glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In karst, areas of limestone bedrock, dry valleys may also result from drainage now taking place cave, underground rather than at the surface. Rift valleys arise principally from tectonics, earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms th ...

Ross Island
Ross Island is an island formed by four volcanoes in the Ross Sea near the continent of Antarctica, off the coast of Victoria Land in McMurdo Sound. Ross Island lies within the boundaries of Ross Dependency, an area of Antarctica claimed by New Zealand. History Discovery Sir James Ross discovered it in 1840, and it was later named in honour of him by Robert F. Scott. Ross Island was the base for many of the early expeditions to Antarctica. It is the southernmost island reachable by sea. Huts built by Scott's and Shackleton's expeditions are still standing on the island, preserved as historical sites. Today Ross Island is home to New Zealand's Scott Base, and the largest Antarctic settlement, the U.S. Antarctic Program's McMurdo Station. Greenpeace established World Park Base on the island and ran it for five years, from 1987 to 1992. Geography Because of the persistent presence of the ice sheet, the island is sometimes taken to be part of the Antarctic mainland. Its are ...
