Crescent Stream
Crescent Stream () is a glacial meltwater stream, long, flowing north from Crescent Glacier to the south-central shore of Lake Fryxell, in Taylor Valley, Victoria Land. It was named in association with Crescent Glacier. The name was suggested by the United States Geological Survey hydrologist Diane McKnight and was approved by the Advisory Committee on Antarctic Names and the New Zealand Geographic Board The New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB) was established by the New Zealand Geographic Board Act 1946, which has since been replaced by the New Zealand Geographic Board (Ngā Pou Taunaha o Aotearoa) Act 2008.

Crescent Glacier (Antarctica)
Crescent Glacier () is a small alpine glacier in Antarctica. It is located just east of Howard Glacier in the Kukri Hills, flowing north into Taylor Valley in Victoria Land. The glacier was studied by U.S. geologist Troy L. Pewe in December 1957, and was so named by him because of its crescent shape when viewed from the floor of Taylor Valley.

Lake Fryxell
Lake Fryxell is a frozen lake long, between Canada Glacier and Commonwealth Glaciers at the lower end of Taylor Valley in Victoria Land, Antarctica. It was mapped in the early 1900s and named during Operation Deep Freeze in the 1950s. There are several forms of algae living in the waters and a weather station located at the lake. Geography Lake Fryxell is deep, making it so the deepest portion of the lake is below sea level. The lake is dammed by Canada Glacier, making it so that it has no natural outflow. It is covered with about of ice, but during the summer months, the ice can clear along the shoreline. There are a few small islands as well as several shallow areas. The average annual ablation is between and , which is significantly lower when compared to other nearby frozen water bodies, such as the waters adjacent to Ross Island. Watershed The watershed contains thirteen streams flowing into the lake, forming a watershed that has an area roughly in size. Where a few of t ...

Taylor Valley
Taylor Valley is the southernmost of the three large McMurdo Dry Valleys in the Transantarctic Mountains, Victoria Land, Antarctica, located west of McMurdo Sound at approximately . The valley extends from Taylor Glacier in the west to McMurdo Sound at Explorers Cove at the northwest head of New Harbour in the east and is about long. It was once occupied by the receding Taylor Glacier, from which it derives its name. Taylor Valley contains Lake Bonney in the west (inward), and Lake Fryxell in the east (coastward), and Lake Hoare, Lake Chad, Lake Popplewell, Mummy Pond and Parera Pond close together between the two. Further east of Lake Bonney is Pearse Valley. Taylor Valley is separated from Wright Valley in the north by Asgard Range, and from Ferrar Glacier in the south by Kukri Hills. At its southernmost end, Taylor Valley becomes Quinn Gully, a mainly ice-free gully, which descends between MacDonald Hills and Hjorth Hill to Explorers Cove in New Harbour. It was named by ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...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.

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rivers Of Victoria Land
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...
