The Coombs Hills (76°47′S 160°0′E) are an area of broken and largely snow-free hills and valleys between Odell Glacier and Cambridge Glacier in Victoria Land. They were discovered in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) and named by them for D.S. Coombs, professor of geology at the University of Otago, New Zealand, who assisted the expedition in obtaining essential petrological equipment. [Wikipedia]
