A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
Mount Tyree (4852m) is the second highest mountain of Antarctica located 13 kilometres northwest of Vinson Massif (4,892 m), the highest peak on the continent. It surmounts Patton Glacier to the north and Cervellati Glacier to the southeast.
The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about 185 km (115 mi) and is 24 to 48 km wide. Many peaks rise over 4,000 m (13,100 ft) and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.
The peak was discovered by the Marie Byrd Land Traverse party of 1957–58 under C.R. Bentley and was named by the Advisory Committee on Antarctic Names for Lieutenant Harvey L. Gardner, U.S. Navy, a pilot in Antarctica in the 1957–58 and 1958–59 seasons who was killed in the crash of a UB-1 Otter airplane at Marble Point on January 4, 1959. [1]
Marie Byrd Land is the portion of West Antarctica lying east of the Ross Ice Shelf and the Ross Sea and south of the Pacific 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 the leading role of the American Rear Admiral Richard E. Byrd in the exploration of this area. The name was originally applied by Admiral Byrd in 1929, in honor of his wife, to the northwestern part of the area, the part that was explored in that year.
The Advisory Committee on Antarctic Names is an advisory committee of the United States Board on Geographic Names responsible for recommending names for features in Antarctica. The United States does not recognise territorial boundaries within Antarctica, so ACAN will assign names to features anywhere within the continent, in consultation with other national nomenclatural bodies where appropriate.
Marble Point is a rocky promontory on the coast of Victoria Land, Antarctica, located at 77° 26' S latitude and 163° 50' E longitude. The United States operates a station at the point. The outpost is used as a helicopter refueling station supporting scientific research in the nearby continental interior such as the McMurdo Dry Valleys. Weather permitting, helicopters are able to fly in and out of the station 24 hours a day during the summer research season.

The United States 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 has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.
The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.
