Tierra del Fuego is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan.
King George Island is the largest of the South Shetland Islands, lying 120 km off the coast of Antarctica in the Southern Ocean. The island was named after King George III.
Isla Grande de Tierra del Fuego also formerly Isla de Xátiva is an island near the southern tip of South America from which it is separated by the Strait of Magellan. The western portion (61.4%) of the island is in Chile, while the eastern portion is in Argentina. It forms the major landmass in an extended group of islands or archipelago also known as Tierra del Fuego.
Southernmost settlements are cities, towns, weather stations or permanent military bases which are farther south than latitude 45°S. They are closely related to the Southern Ocean or either the Roaring Forties or Furious Fifties. Antarctic bases are excluded due to not having a permanent population.
Puerto Williams is a city, port and naval base on Navarino Island in Chile, and is also the southernmost populated settlement in the world. It faces the Beagle Channel. It is the capital of the Chilean Antarctic Province, one of four provinces in the Magellan and Chilean Antarctica Region, and administers the communes of Chilean Antarctic Territory and Cabo de Hornos. It has a population of 2,874, including both naval personnel and civilians. Puerto Williams claims the title of world's southernmost city. The settlement was founded in 1953, and was first named Puerto Luisa. The town was later named after John Williams Wilson, a British man who founded Fuerte Bulnes, the first settlement in the Strait of Magellan. It has served primarily as a naval base for Chile. The Chilean Navy runs the Guardiamarina Zañartu Airport and hospital, as well as nearby meteorological stations. Since the late 20th century, the number of navy personnel has decreased in Puerto Williams and the civilian population has increased. In that period, tourism and support of scientific research have contributed to an increase in economic activity.
Beagle Channel is a strait in the Tierra del Fuego Archipelago, on the extreme southern tip of South America between Chile and Argentina. The channel separates the larger main island of Isla Grande de Tierra del Fuego from various smaller islands including the islands of Picton, Lennox and Nueva; Navarino; Hoste; Londonderry; and Stewart. The channel's eastern area forms part of the border between Chile and Argentina and the western area is entirely within Chile.
Antártica Chilena Province is the southernmost of the four provinces in Chile's southernmost region, Magallanes and Antártica Chilena Region (XII). The capital is Puerto Williams. The province comprises the extreme southern part of Isla Grande de Tierra del Fuego, the islands south and west of Isla Grande, and Chile's claims in Antarctica. The province is administratively divided into two communes (comunas): Cabo de Hornos, located at the southern tip of South America, and Antártica, a wedge-shaped claim of Antarctica, which is not internationally recognized. Its total area of 1,265,853.7 km2 (488,749 sq mi) makes it almost twice as large as all other provinces of Chile combined.
Hoste Island is one of the southernmost islands in Chile, lying south, across the Beagle Channel, from Isla Grande de Tierra del Fuego and west of Navarino Island, from which it is separated by the Murray Channel. It is named after William Hoste, one of Lord Nelson's protégés. In Magellania, Jules Verne described an imaginary republic on the island.
Picton, Lennox and Nueva form a group of three islands at the extreme southern tip of South America, in the Chilean commune of Cabo de Hornos in Antártica Chilena Province, Magallanes and Antártica Chilena Region. Located in the Tierra del Fuego archipelago, they lie east of Navarino Island and are separated from the Argentine part of Isla Grande in the north by the Beagle Channel. They have an area of 170.4 km2 (Lennox), 105.4 km2 (Picton), 120.0 km2 (Nueva).
Tierra del Fuego Province is one of four provinces in the southern Chilean region of Magallanes and Antártica Chilena (XII). It includes the Chilean or western part of the main island of Tierra del Fuego, except for the part south of the Cordillera Darwin, which is in Antártica Chilena Province.
Navarino Island is a Chilean island located between Isla Grande de Tierra del Fuego, to the north, and Cape Horn, to the south. The island forms part of the Commune of Cabo de Hornos, the southernmost commune in Chile and in the world, belonging to Antártica Chilena Province in the XII Region of Magallanes and Chilean Antarctica. Its population is concentrated primarily in the communal capital, Puerto Williams, and in small settlements like Puerto Navarino, Río Guanaco and Puerto Toro. The highest point of the island is Pico Navarino at 1,195 m (3,921 ft). The island is a popular destination for fly-fishers.
The Murray Channel is a channel of Chile located in the Commune of Cabo de Hornos, in the Antártica Chilena Province of the Magallanes y la Antártica Chilena Region. It separates Hoste Island from Navarino Island and is bounded by the Beagle Channel to the north. The salinity of the Murray Channel is approximately 31.8 parts per thousand.
The Diocese of Punta Arenas is a suffragan diocese of the Archdiocese of Puerto Montt, in Chile. Its current bishop is Mgr. Óscar Hernán Blanco Martínez, O.M.D.
Cape Shirreff is a prominent cape at the north end of the rocky peninsula which separates Hero Bay and Barclay Bay on the north coast of Livingston Island, in the South Shetland Islands of Antarctica. The cape was named by Edward Bransfield in 1820 after Captain William H. Shirreff, the British commanding officer in the Pacific at that time.
The islands of Chile encompass the various islands that the government of Chile has sovereignty over. By far the majority of these are the islands in the south of the country. Chile has one of the world's longest coastlines, and one of the most dangerous for boats; it is more than 4,000 kilometres (2,500 mi) long and has at least 43,471 islands.
Muellerella is a genus of lichenicolous lichens in the family Verrucariaceae. The genus has a widespread distribution, especially in northern temperate areas, and contains species that live on other lichens, or on liverworts.
The Martial Mountains are a mountain range in Isla Grande de Tierra del Fuego, an island of Argentina and Chile. The mountain range is located east of Cordillera Darwin, just north of Ushuaia city in Argentina, along the Beagle Channel strait.
