Flatiron Valley
Flatiron Valley is a north-south valley including a sub-glacial lake, located in the south part of the Ganymede Heights, marginal to Jupiter Glacier, situated in eastern Alexander Island, Antarctica. The name derives from field work in 1978–79 by the Department of Geography, University of Aberdeen, Scotland, with British Antarctic Survey support. It was named from the triangular slope facets between prominent gullies on the west side of the valley. The site lies within Antarctic Specially Protected Area (ASPA) No.147.

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 ...

Ganymede Heights
The Ganymede Heights consist of rounded ridges with extensive rock outcrops rising to about , between Jupiter Glacier and Ablation Valley on the eastern side of Alexander Island, Antarctica. They were mapped by the Directorate of Overseas Surveys from satellite imagery supplied by the US National Aeronautics and Space Administration in cooperation with the US Geological Survey. They were named by the UK Antarctic Place-Names Committee from association with Jupiter Glacier after Ganymede, one of the satellites of the planet Jupiter. The feature also lies close to the Galileo Cliffs, which were named for the moon's discoverer, Galileo Galilei Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name was pronounced (, ). He wa ... (1564-1642). The site lies within Antarctic Specially Protected Area (ASPA) No.147. Se ...

Jupiter Glacier
Jupiter Glacier () is a glacier on the east coast of Alexander Island, Antarctica, long and wide at its mouth, which flows east into George VI Sound to the south of Ablation Valley. It was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition, and was named for the planet Jupiter by the Falkland Islands Dependencies Survey following their surveys in 1948 and 1949. The glacier lies north of Planet Heights, although Jupiter Glacier is not situated within the mountain range, the glacier (along with many other nearby glaciers named after planets of the Solar System) is so named under the association of Planet Heights even though it is not directly a glacier located within this mountainous range.

Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

Ablation Valley
Ablation Valley, also known as Ablation Bay, is a mainly ice-free valley on the east coast of Alexander Island, long, which is entered immediately south of Ablation Point, opens on George VI Sound and lies immediately north of Ganymede Heights. It was first photographed from the air on 23 November 1935 by Lincoln Ellsworth and mapped from these photographs by W.L.G. Joerg. It was first visited and surveyed in 1936 by the British Graham Land Expedition (BGLE), and given the name "Ablation" by them because of the relatively small amounts of snow and ice found there. The site lies within Antarctic Specially Protected Area (ASPA) No.147. Climate The climate of the area is affected by easterly-moving cyclonic depressions of the Southern Ocean. These depressions make the weather relatively mild; bring strong northerly winds and a heavy cloud cover to the region. The climate is also characterized by continental north to northwesterly flow of cold anticyclone air from the West Antarcti ...
