An entirely volcanic island in the Ross Sea off the coast of Antarctica in McMurdo Sound at 77°30'S 168°00'E, Ross Island is made up of four volcanoes including Mount Erebus, the worlds most southerly active volcano 3,794m (12,448ft) high and one of a very few worldwide with a permanent lava lake in the crater. Ross Island gives the impression of being part of the mainland as there is a permanent ice connection to the Ross Ice Shelf along the southern edge.
Ross Island was discovered by Sir James Clark Ross in 1841 and was thought to be part of the mainland. It was found to be an island by the British National Antarctic Expedition in 1901-04 and named for Ross by Captain Scott. Mount Erebus was named by Ross for his ship. The extinct volcano Mount Terror on Ross Island was named for Ross's other ship on his expedition at the time.
Ross Island has played a large role in the history and exploration of Antarctica. It has three historic huts that were built and used by the explorers Scott and Shackleton in the Heroic Age of Antarctic Exploration from 1898 to 1922.
There are two currently active scientific stations at the end of the Hut Point Peninsula, the American McMurdo Station which was established in 1956 and the New Zealand Scott Base established in 1957.

An ice tongue forms where a valley glacier moves quickly out to sea, the ice is freshwater ice fed in this case by accumulated snow from the slopes of Mount Erebus which floats when it meets the sea.
