Brown Bluff - Photo by Tam Warner Minton

Brown Bluff is a million-year-old volcano which gets its name from its brown/black slopes. Known as a tuya, a flat-topped and steep-sided volcano that has erupted from within a glacier, it is a very unusual sight, and in fact there are quite rare worldwide. This volcano island has a pebble beach where you can get up close to Adelie penguins as they make their way out to sea. (South Western Coast, Antarctic Sound, Antarctica)
