The French Southern and Antarctic Lands is an overseas territory of France. It consists of:
- Adélie Land, the French claim on the continent of Antarctica.
- Crozet Islands, a group in the southern Indian Ocean, south of Madagascar.
- Kerguelen Islands, a group of volcanic islands in the southern Indian Ocean, southeast of Africa.
- Saint Paul and Amsterdam Islands, a group to the north of the Kerguelen Islands.
- Scattered Islands, a dispersed group of islands around the coast of Madagascar.
The Kerguelen Islands, also known as the Desolation Islands, are a group of islands in the sub-Antarctic constituting one of the two exposed parts of the Kerguelen Plateau, a large igneous province mostly submerged in the southern Indian Ocean. They are among the most isolated places on Earth, located more than 3,300 kilometres from Madagascar. 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.
The geography of New Caledonia (Nouvelle-Calédonie), an overseas collectivity of France located in the subregion of Melanesia, makes the continental island group unique in the southwest Pacific. Among other things, the island chain has played a role in preserving unique biological lineages from the Mesozoic. It served as a waystation in the expansion of the predecessors of the Polynesians, the Lapita culture. Under the Free French it was a vital naval base for Allied Forces during the War in the Pacific.
The geography of France consists of a terrain that is mostly flat plains or gently rolling hills in the north and 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.
The Crozet Islands are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands.
Île Amsterdam, also known as Amsterdam Island and New Amsterdam (Nouvelle-Amsterdam), is an island of the French Southern and Antarctic Lands in the southern Indian Ocean that together with neighbouring Île Saint-Paul 90 km to the south forms one of the five districts of the territory.
The Piton des Neiges is a 3,069 m (10,069 ft) shield volcano on Réunion, one of the French volcanic islands in the Mascarene Archipelago in the southwestern Indian Ocean. It is located about 800 kilometres (500 mi) east of Madagascar. Piton des Neiges is the highest point on Réunion and is considered to be the highest point in the Indian Ocean. The volcano was formed by the Réunion hotspot and emerged from the sea about two million years ago. Now deeply eroded, the volcano has been inactive for 20,000 years and is surrounded by three massive crater valleys, the Cirques. The Piton des Neiges forms the northwestern two-thirds of Réunion, with the very active Piton de la Fournaise comprising the rest. As its name suggests, snow is occasionally seen on its summit in winter. The Piton des Neiges is ranked 14th by topographic isolation.
Île Saint-Paul is an island forming part of the French Southern and Antarctic Lands in the Indian Ocean, with an area of 6 km2. The island is located about 90 km (56 mi) south of the larger Île Amsterdam, 1,300 kilometres (810 mi) northeast of the Kerguelen Islands, and 3,000 km (1,900 mi) southeast of Réunion.
Mawson Peak is an active volcanic summit of the Big Ben massif on Heard Island, an external Australian territory in the Indian Ocean.
The Îlots des Apôtres or Îles des Apôtres are a group of small and uninhabited rocky islands in the north-western part of the Crozet Archipelago in the southern Indian Ocean, 10 km (6.2 mi) north of Île aux Cochons. Their total area is about 2 km2 (0.77 sq mi).
The Courbet Peninsula is a peninsula in northeastern Grande Terre Island, the main island of the subantarctic Kerguelen Archipelago, Southern Indian Ocean. In the south of the peninsula is Port-aux-Français, the principal station of the archipelago.
An ultra-prominent peak, or ultra for short, is a mountain summit with a topographic prominence of 1,500 metres (4,900 ft) or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence.
The topographic isolation of a summit is the minimum distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point. It can be calculated for small hills and islands as well as for major mountain peaks and can even be calculated for submarine summits.
The Plateau des Tourbières comprises the highest upland region of Amsterdam Island, a small French territory in the southern Indian Ocean. Over 500 m above sea level, it contains the island's highest peaks: Mont de la Dives (881 m), Grande Marmite (742 m) and Mont Fernand (731 m).
Île des Pingouins, or Penguin Island, is an uninhabited island in the subantarctic Crozet Archipelago of the southern Indian Ocean. With an area of only 3 km2 (1 sq mi) it is one of the smaller islands of the group. Administratively, it is part of the French Southern and Antarctic Lands. It is an important nesting site for seabirds.
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.
Mont Choungui is a distinctively conical volcanic mountain in the southern part of the French island of Mayotte, in the Comoro archipelago of the western Indian Ocean. It is the second highest point of the island at 593 m (1,946 ft), the highest being Mont Bénara, and is visible from far out at sea.
