The Gallieni Massif (French : Massif Gallieni) is a mountain range in Grande Terre, the main island of Kerguelen in the French Southern Territories zone of the Southern Indian Ocean. [2]
This range is located in the Gallieni Peninsula, fringing the southern coast. The highest point of the massif is the 1,850 metres (6,070 ft) high Mont Ross, a stratovolcano that is also the highest point of the Kerguelen Archipelago.
Other important summits of the range are 1,721 metres (5,646 ft) high Petit Ross, 1,063 metres (3,488 ft) high Dôme du Père Gaspard and the 995 metres (3,264 ft) high Grand Gendarme. The range also includes a number of glacial formations, among which the Buffon Glacier, the La Pilatte Glacier ,the Néves Glacier and the Sélé Glacier deserve mention. [3]
The Territory of Heard Island and McDonald Islands is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica. The group's overall land area is 372 km2 (144 sq mi) and it has 101.9 km (63 mi) of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen Plateau in the Indian Ocean and have been an Australian territory since 1947.
The Kerguelen Islands, also known as the Desolation Islands, are a group of islands in the sub-Antarctic region. They are among the most isolated places on Earth, with the closest territory being the Heard Island and McDonald Islands territory of Australia located at roughly 450 km (240 nmi), and the nearest inhabited territory being Madagascar at more than 3,300 kilometres in distance. The islands, along with Adélie Land, the Crozet Islands, Amsterdam and Saint Paul islands, and France's Scattered Islands in the Indian Ocean, are part of the French Southern and Antarctic Lands and are administered as a separate district.
Mont Blanc is the highest mountain in the Alps and Western Europe, and the highest mountain in Europe outside the Caucasus Mountains, rising 4,805.59 m (15,766 ft) above sea level, located on the Franco-Italian border. It is the second-most prominent mountain in Europe, after Mount Elbrus, and the 11th most prominent mountain in the world.
The geography of France consists of a terrain that is mostly flat plains or gently rolling hills in the north and the west and mountainous in the south and the east. Metropolitan France has a total size of 551,695 km2 (213,011 sq mi). It is the third-largest country in Europe by area and the largest in Western Europe.
Vinson Massif is a large mountain massif in Antarctica that is 21 km (13 mi) long and 13 km (8 mi) wide and lies within the Sentinel Range of the Ellsworth Mountains. It overlooks the Ronne Ice Shelf near the base of the Antarctic Peninsula. The massif is located about 1,200 kilometres (750 mi) from the South Pole. Vinson Massif was discovered in January 1958 by U.S. Navy aircraft. In 1961, the Vinson Massif was named by the Advisory Committee on Antarctic Names (US-ACAN), after Carl G. Vinson, United States congressman from the state of Georgia, for his support for Antarctic exploration. On November 1, 2006, US-ACAN declared Mount Vinson and Vinson Massif to be separate entities. Vinson Massif lies within the unrecognised Chilean claim under the Antarctic Treaty System.
Kebnekaise is the highest mountain in Sweden. The Kebnekaise massif, which is part of the Scandinavian mountain range, has two main peaks. The glaciated southern peak used to be the highest at 2,120 metres (6,960 ft) above sea level, but has shrunk by 24 meters during the last 50 years, making the northern icefree peak at 2,096.8 metres (6,879 ft) the highest. Kebnekaise lies in Swedish Lapland, about 150 kilometres (93 mi) north of the Arctic Circle and west of Kiruna near the Kungsleden hiking trail between Abisko and Hemavan.
Aneto is the highest mountain in the Pyrenees and in Aragon, and Spain's third-highest mountain, reaching a height of 3,404 metres. It stands in the Spanish province of Huesca, the northernmost of the three Aragonese provinces, 6 kilometres south of the France–Spain border. It forms the southernmost part of the Maladeta massif.
The Diablerets are a huge ice-covered mountain massif of the Alps, culminating at the Sommet des Diablerets (VS) at 3,216 metres (10,551 ft) above sea level and almost straddling the border between the Swiss cantons of Vaud (VD) and Valais (VS). The northeastern part of the massif stretches also into the canton of Bern (BE).
The Queen Maud Mountains are a major group of mountains, ranges and subordinate features of the Transantarctic Mountains, lying between the Beardmore and Reedy Glaciers and including the area from the head of the Ross Ice Shelf to the Antarctic Plateau in Antarctica. Captain Roald Amundsen and his South Pole party ascended Axel Heiberg Glacier near the central part of this group in November 1911, naming these mountains for the Norwegian queen Maud of Wales.
The Royal Society Range is a majestic range of mountains in Victoria Land, Antarctica, rising to 4,025 metres (13,205 ft) along the west shore of McMurdo Sound between the Koettlitz, Skelton and Ferrar Glaciers. They are south of the Kukri Hills, southeast of the Quartermain Mountains, and northeast of the Worcester Range.
Monte Rosa is a mountain massif in the eastern part of the Pennine Alps, on the border between Italy and Switzerland (Valais). The highest peak of the massif, amongst several peaks of over 4,000 m (13,000 ft), is the Dufourspitze, the second highest mountain in the Alps and western Europe, after Mont Blanc. The east face of the Monte Rosa towards Italy has a height of about 2,400 metres (7,900 ft) and is the highest mountain wall of the Alps.
The Grand Combin is a mountain massif in the western Pennine Alps in the canton of Valais. At a height of 4,309 metres (14,137 ft) the summit of Combin de Grafeneire is one of the highest peaks in the Alps and the second most prominent of the Pennine Alps. The Grand Combin is also a large glaciated massif consisting of several summits, among which three are above 4000 metres. The highest part of the massif is wholly in Switzerland, although the border with Italy lies a few kilometres south.
The Barre des Écrins is a mountain in the French Alps with a peak elevation of 4,102 metres (13,458 ft). It is the highest peak of the Massif des Écrins and the Dauphiné Alps and the most southerly alpine peak in Europe that is higher than 4,000 metres. It is the only 4,000-metre mountain in France that lies outside the Mont Blanc Massif. Before the annexation of Savoy in 1860 it was the highest mountain in France.
The Mont Blanc massif is a mountain range in the Alps, located mostly in France and Italy, but also straddling Switzerland at its northeastern end. It contains eleven major independent summits, each over 4,000 metres (13,123 ft) in height. It is named after Mont Blanc, the highest point in western Europe and the European Union. Because of its considerable overall altitude, a large proportion of the massif is covered by glaciers, which include the Mer de Glace and the Miage Glacier – the longest glaciers in France and Italy, respectively.
The Cook Ice Cap or Cook Glacier is a large ice cap in the Kerguelen Islands in the French Southern Territories zone of the far Southern Indian Ocean.
Mont Ross is a stratovolcano, the highest mountain in the Kerguelen Islands at 1,850 metres (6,070 ft). It is located in the Gallieni Massif, at the end of the Gallieni Peninsula, east of Baie Larose on the main island of Grande Terre. The volcano is composed primarily of trachybasalt and was active during the late Pleistocene. Eruptives have been dated between 2 million years to 100,000 years old.
The Watkins Range is Greenland's highest mountain range. It is located in King Christian IX Land, Sermersooq municipality.
Baie Larose, or Larose Bay in English, is a bay of Grande Terre, the main island of the subantarctic Kerguelen archipelago, a French territory in the southern Indian Ocean. It is important as a breeding site for seabirds, especially penguins.
Les Îles Leygues or the Leygues Islands, occasionally called « les Îles Swain », are a group of small islands and islets that are part of the subantarctic Kerguelen archipelago, a French territory in the southern Indian Ocean.
The geography of the Heard Island and McDonald Islands (HIMI) refers to the geography of Heard Island and the McDonald Islands, one of the most remote places on earth. The islands belong to Australia and are located 4,000 kilometres (2,485.5 mi) southwest of the mainland in the Southern Ocean. These subantarctic islands were transferred to Australia by the United Kingdom in 1947. They lie between Madagascar and Antarctica.
