Cecret Lake
Cecret Lake (pronounced like ''Secret'') is a small alpine lake in Albion Basin which is within the town limits of Alta in the U.S. state of Utah. This area is also part of the Wasatch National Forest. Cecret Lake is also a protected watershed for Salt Lake City. The United States Geological Survey officially spells the name of this lake as "Cecret Lake". The lake can be accessed in the summer by parking on the main road in Little Cottonwood Canyon and hiking up a dirt trail to the lake. The lake is surrounded by quartz monzonite, commonly mistaken for granite rock. Cecret Lake is also surrounded by the Alta and Snowbird Snowbird is a common name for the dark-eyed junco (''Junco hyemalis'').

Lake Hodgson
Hodgson Lake is a perennially ice-covered freshwater lake, which is about 2 km (1.2 mi) long by about 1.5 km (0.93 mi) wide. It is located within the southern part of Alexander Island, west of Palmer Land in Antarctica, at approximately 72°S latitude and 68°W longitude. This lake has a 93.4 m (306 ft) deep water column that lies sealed beneath a 3.6 to 4.0 m (12 to 13 ft) thick perennial lake ice. The lake is an ultra- oligotrophic lake with very low nutrient content and very low productivity. There is no detectable life living in Hodgson Lake. The lake extends eastward into George VI Sound and the George VI Ice Shelf making it adjacent to the sound. The northern side of this lake is bounded by the Saturn Glacier, which flows east into George VI Sound. The lake lies next to and southeast of Citadel Bastion, a pre-eminent mountain on Alexander Island.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . ...

Ablation Lake
Ablation Lake is a proglacial tidal lake in Ablation Valley, Alexander Island, Antarctica, with stratified saline and fresh water and depths exceeding . The feature is dammed in the upper portion by ice that pushes into the lake from the adjacent George VI Ice Shelf. It is named after Ablation Valley following British Antarctic Survey (BAS) limnological research from 1973. The site lies within Antarctic Specially Protected Area (ASPA) No.147. The lake has a sub-ice channel connecting it to George VI Sound, and is approximately below the surface of the ice.

United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features *Anckorn Nunataks, named after J. F. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth an ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown m ...

Satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by pr ...

Ordnance Survey International
The Ordnance Survey International or Ordnance Survey Overseas Directorate its predecessors built an archive of air photography, map and survey records for the United Kingdom from 1946 to 1999. The Ordnance Survey International Collection (formerly the Ordnance Survey International Library) held mapping records that were acquired outside the UK. Although the international division opened in 1946, the OS had been involved in overseas work for almost a century (notably the 1864-65 Ordnance Survey of Jerusalem). The agency was closed in 2001. History The agency In 1946 the ''Directorate of Colonial Surveys'' (DCS) was established by the Colonial Office to provide a central survey and mapping organisation for British colonies and protectorates. In 1957, with the imminent decolonisation of many British territories, it was renamed the ''Directorate of Overseas Surveys'' (DOS). Government reviews during the 1970s led to it being merging into the Ordnance Survey (OS) in 1984 whence it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars Glacier
Mars Glacier is a glacier in the southeastern corner of Alexander Island, Antarctica, long and wide, flowing south into the George VI Ice Shelf. The glacier lies between Two Step Cliffs and Phobos Ridge. Mars Glacier was first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. It was first surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the UK Antarctic Place-Names Committee for the planet Mars, the fourth planet from the sun in the Solar System. Although Mars Glacier is not located within the Planet Heights mountain range, it lies nearby, and its name derives from it, along with many other nearby glaciers and landmarks located here which are named after planets, satellites and astrophysicists. See also * Mercury Glacier * Saturn Glacier * Venus Glacier * Two Step Moraine Two Step Moraine () is a small area of homogeneous fine morainic debris, in the sout ...
