The ice-covered volcano of Mount Erebus (3394 m) dominates the landscape of Ross Island, and formed an iconic backdrop to the early 20th century expeditions of Scott and Shackleton, as well as New Zealand’s Scott Base (from where this view was taken) and America’s McMurdo Station. This volcano is the southernmost in the world, and the fact that it is active is evident from the plume of steam at the summit.
