McDonald Heights
The McDonald Heights () are broad, mainly snow-covered heights about long and rising over between Cape Burks and Morris Head on the coast of Marie Byrd Land, Antarctica. The heights are bounded southward by Hull Glacier, Kirkpatrick Glacier and Johnson Glacier. The feature was photographed from aircraft of the United States Antarctic Service, 1939–1941, was observed and partially mapped from during February 1962, and was mapped in detail by the United States Geological Survey in 1965. The heights were named by the Advisory Committee on Antarctic Names after Captain Edwin A. McDonald, U.S. Navy, Deputy Commander of the U.S. Naval Support Force, Antarctica, in 1962, and Commander of the Task Unit that explored this coast aboard ''Glacier'' in February 1962.

Kirkpatrick Glacier
Kirkpatrick Glacier () is a tributary glacier about long, flowing west along the south side of the McDonald Heights to enter the east side of Hull Glacier near the coast of Marie Byrd Land, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–65, and was named by the Advisory Committee on Antarctic Names for Commander Thomas W. Kirkpatrick, United States Coast Guard, Ship Operations Officer, U.S. Naval Support Force, Antarctica, during Operation Deep Freeze 1972 and 1973.

Johnson Glacier
Johnson Glacier () is a glacier flowing north between the McDonald Heights and Bowyer Butte to merge with the Getz Ice Shelf on the coast of Marie Byrd Land, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–65, and was named by the Advisory Committee on Antarctic Names for Roland L. Johnson, Boatswain's Mate, U.S. Navy, a crew member of the during exploration of this coast in the 1961–62 season.

Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of (including Eights Coast, immediately east of Marie Byrd Land). In 1939, United States President Frankl ...

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 hundredt ...

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] |

Byrd Station
The Byrd Station is a former research station established by the United States during the International Geophysical Year by U.S. Navy Seabees during Operation Deep Freeze II in West Antarctica. History A joint Army, Navy, Air Force, and Marines operation supported an overland tractor train traverse that left out of Little America V in late 1956 to establish the station. The train was led by Army Major Merle Dawson and completed a traverse of over unexplored country in Marie Byrd Land to blaze a trail to a spot selected beforehand. The station consisted of a set of four prefabricated buildings and was erected in less than one month by U.S. Navy Seabees. It was commissioned on January 1, 1957. The original station ("Old Byrd") lasted about four years before it began to collapse under the snow. Construction of a second underground station in a nearby location began in 1960, and it was used until 1972. The Operation Deep Freeze activities were succeeded by "Operation Deep Freez ...

Mountain Passes Of Antarctica
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
