     "abstract": "The highest peak in Antarctica, the Vinson Massif (78\u00ba35\u2019S, 85\u00ba25\u2019W), is at an elevation of 4892 m (16,046 \nft), as determined in 2004. Measurements of the elevation have fluctuated over the years, from its earliest surveyed \nelevation of 5140 m (16,859 ft), to its present height. Vinson Massif and three of its near neighbors in the Sentinel \nRange of the Ellsworth Mountains are the highest peaks in Antarctica, making them a favorite objective of \nmountaineers. Well over 1,100 people have climbed Vinson since the first ascent by a team in the 1966-67 austral \nsummer. The range is composed of Crashsite quartzite, making the Sentinel\u2019s very resistant to erosion. Very accurate \nelevations have been achieved annually by GPS mapping done by a climbing team sponsored by the Omega \nFoundation, active in Antarctica since 1998. The Craddock Massif now includes Mt. Craddock, the ninth highest peak \nin Antarctica, at 4368 m (14,327 ft). Both are named for Campbell Craddock*, a U.S. geologist active in Antarctic \nresearch beginning in 1959-60.",
