Gamburtsev Mountains

subglacial mountains in the central part of eastern Antarctica. They extend for 1,200-1,300 km in the shape of an arc, stretching south, between 72° and 82° S lat. and 30° and 90° E long. They are 200-500 km wide. The highest known peaks are 2,990 m and 3,390 m. The ice above them is at least 600 m thick. The mountains were discovered by a Soviet Antarctic expedition in 1958 and named for G. A. Gamburtsev.
