Basalt Lake
Basalt Lake is a small freshwater lake surrounded by three basalt outcrops with ‘organ-pipe’ formations in their rocks, situated in the central part of the ice-free Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. and draining through a stream southwards into Bransfield Strait. The feature is descriptively named from the surrounding rock formations. Location Basalt Lake is centred at which is northeast of Sealer Hill, east of Usnea Plug, east-southeast of Chester Cone, west-southwest of Tsamblak Hill and west-northwest from Negro Hill (British mapping in 1968, detailed Spanish mapping in 1992, and Bulgarian mapping in 2005 and 2009).

Livingston Island
Livingston Island (Russian name ''Smolensk'', ) is an Antarctic island in the Southern Ocean, part of the South Shetlands Archipelago, a group of Antarctic islands north of the Antarctic Peninsula. It was the first land discovered south of 60° south latitude in 1819, a historic event that marked the end of a centuries-long pursuit of the mythical ''Terra Australis Incognita'' and the beginning of the exploration and utilization of real Antarctica. The name Livingston, although of unknown derivation, has been well established in international usage since the early 1820s. Geography Livingston Island is situated in West Antarctica northwest of Cape Roquemaurel on the Antarctic mainland, south-southeast of Cape Horn in South America, southeast of the Diego Ramírez Islands (the southernmost land of South America), due south of the Falkland Islands, southwest of South Georgia Islands, and from the South Pole.L.

South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byers Peninsula
Byers Peninsula is a mainly ice-free peninsula forming the west end of Livingston Island in the South Shetland Islands of Antarctica. It occupies , borders Ivanov Beach to the northeast and is separated from Rotch Dome on the east by the ridge of Urvich Wall. The peninsula features more than 60 meltwater streams and as many lakes, notably Midge Lake, Limnopolar Lake and Basalt Lake. Byers Peninsula has a regime of special environmental protection under the Antarctic Treaty System and requires a permit to enter. History The feature was named by the UK Antarctic Place-names Committee in 1958 for James Byers, a New York shipowner who tried unsuccessfully in August 1820 to induce the United States Government to found a settlement in and take possession of the South Shetland Islands. Byers organized and sent out a fleet of American sealers from New York to the South Shetland Islands in 1820–21. It was visited by early 19th century American and British sealers who came almost exclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bransfield Strait
Bransfield Strait or Fleet Sea ( es, Estrecho de Bransfield, Mar de la Flota) is a body of water about wide extending for in a general northeast – southwest direction between the South Shetland Islands and the Antarctic Peninsula. History The strait was named in about 1825 by James Weddell, Master, Royal Navy, for Edward Bransfield, Master, RN, who charted the South Shetland Islands in 1820. It is called ''Mar de la Flota'' by Argentina. On 23 November 2007, the MS ''Explorer'' struck an iceberg and sank in the strait; all 154 passengers were rescued and no injuries were reported. Description The undersea trough through the strait is known as Bransfield Trough (). The basin is about 400 km long and 2 km deep, between the South Shetland Island Arc and the Antarctic Peninsula. It was formed by rifting behind the islands, which began about 4 million years ago. Ongoing rifting has caused recent earthquakes and volcanism. The Strait hosts a chain of submerged seam ...

Sealer Hill
Sealer Hill is a hill rising to 70 m in the southwest part of Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. It surmounts Nikopol Point and Sevar Point to the east-southeast and west-southwest, respectively. The area was inhabited by 19th century sealers. The feature was so named following geological work by BAS in 1975–76, from the presence of at least three crude stone huts built by sealers below the hill. Location The hill is located at , which is 1.28 km west-northwest of Nikopol Point, 1.83 km east-northeast of Sevar Point, 3.49 km east by north of Devils Point, 2.8 km southeast of Point Smellie, 4.07 km southwest of Basalt Lake and 3.96 km south-southwest of Chester Cone Chester Cone is the ice-free peak rising to 188 m in the central part of Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica surmounting Midge Lake to the northwest.

Usnea Plug
Usnea Plug is a volcanic plug, 30 m from base to summit, rising to 117 m in the interior of Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. The area was known to 19th century sealers. The feature's name derives from the genus of lichen, Usnea, prevalent on the plug and in this vicinity, and results from geological work by an American field party in early 1969. Location The hill is located at which is 790 m southwest of Chester Cone, 3.47 km north of Nikopol Point, 5.54 km northeast of Devils Point and 2.77 km east by south of Laager Point Laager Point is a conspicuous headland extending out from President Beaches on Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica facing Astor Island.
