Morrow climbed Mount Everest, the highest peak of the world, with the Canadian Mount Everest Expedition 1982. Between 1977 and 1986 he climbed the Seven Summits in the more difficult Carstensz-Version (Messner list). He wrote a book about this process, Beyond Everest: Quest for the Seven Summits, in which he argued the veracity of the Carstensz-Version over the Bass List.
