Mount Erebus is an ultra mountain and the planet's southernmost volcano. Sheathed in ice, with hundreds of ice caves and a lava lake, its name is synonymous with the tragic 1979 air accident. Polar and mountain photographer Colin Monteath's new book Erebus The Ice Dragon; A portrait of an Antarctic volcano blends history, science, art and adventure set alongside stunning amages. Colin has worked in Antarctica for 32 seasons, and was involved in the recovery operation after the air crash on Ross Island.
