	Williamson Glacier Williamson Glacier () is a glacier draining northeastward from Law Dome into Colvocoresses Bay. Delineated by G.D. Blodgett (1955) from air photos taken by U.S. Navy Operation Highjump (1946–47). Named by Advisory Committee on Antarctic Names (US-ACAN) after John G. Williamson, crew member on the sloop Vincennes of the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes.

	Colvocoresses Bay Colvocoresses Bay () is a bay formed by the right angle of the Budd Coast at Williamson Glacier. The bay is over wide at the entrance and is occupied by glacier tongues and icebergs from Williamson Glacier and Whittle Glacier. It was delineated by G.D. Blodgett (1955) from aerial photographs taken by U.S. Navy Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names for George Colvocoresses, midshipman on the sloop ''Vincennes'' during the United States Exploring Expedition (1838–42) under Charles Wilkes.

	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]
picture info	Ice Tongues Of Antarctica Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
