The highest peak in Antarctica, Vinson Massif (78º35’S, 85º25’W), is at an elevation of 4892 m (16,046 ft – 2004 measurement). Measurements of the elevation have fluctuated over the years, from its earliest figure of 5140 m (16,859 ft), to its present figure. Vinson Massif and three of its near neighbors in the SentinelRange of the EllsworthMountains are the highest peaks in Antarctica, making them a favorite objective of mountaineers. Well over 1,000 people have climbed Vinson since the first ascent in the 1966-67 austral summer. The spectacular topography of the range is a factor of the geologic rock type and glacial erosion. Very accurate elevations have been achieved annually by GPS mapping done by a climbing team sponsored by Omega Foundation, active in Antarctica since 1998. Craddock Massif includes Mt. Craddock (after Campbell Craddock*), the ninth highest peak in Antarctica, at 4368 m (14,327 ft).
