Vinson Massif was discovered in January 1958 by U.S. Navy aircraft. In 1961, the Vinson Massif was named by the Advisory Committee on Antarctic Names (US-ACAN), after Carl G. Vinson, United States congressman from the state of Georgia, for his support for Antarctic exploration. On November 1, 2006, US-ACAN declared Mount Vinson and Vinson Massif to be separate entities.[1][2] Vinson Massif lies within the Chilean claim under the Antarctic Treaty System.
