Mathewson Point ( 74°23′S132°33′W / 74.383°S 132.550°W Coordinates: 74°23′S132°33′W / 74.383°S 132.550°W ) is a steep, rocky point at the northern tip of Shepard Island, which lies on the seaward edge of the Getz Ice Shelf, Marie Byrd Land, Antarctica. The point, the site of an Adélie penguin rookery, was charted by personnel of the USS Glacier on February 4, 1962, and was named by the Advisory Committee on Antarctic Names for Lieutenant David S.

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.
Shepard Island or John Shepard Island is an island about 18 km (11 mi) long, lying 10 km (6 mi) west of Grant Island off the coast of Marie Byrd Land, Antarctica. Shepard Island is ice capped except at its northern, seaward side, and is almost wholly embedded in the Getz Ice Shelf. Shepard Island was discovered by the United States Antarctic Service (USAS) Expedition (1939–1941) and named for John Shepard, Jr., a contributor to the expedition.

Several large islands are partially or wholly embedded in the ice shelf, pinning the calving front.

Deception Glacier is a glacier between the Warren Range and the Boomerang Range, flowing south into upper Mulock Glacier. It was so named by the New Zealand party of the Commonwealth Trans-Antarctic Expedition (1956–58) because it appears to lead directly into Skelton Neve but instead drains southward.

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.
