Mount Erebus stratovolcano is the highest and most active volcano of Antarctica, one of the Volcanic Seven Summits, and the largest of 4 volcanoes that form the roughly triangular Ross Island (Mt Erebus, and the extinct Mt. Bird to the north, Mt. Terra Nova and Mt. Terror to the east).
Hut Point Peninsula to the south is the location of McMurdo Station (the main US base) and Scott Base (the main New Zealand base).
Mount Erebus volcano, located on the western half of Ross Island, Antarctica, is the world's southernmost historically active volcano and famous for its active boiling lava lake.
Its summit temperature averages between -20 (summer) and -50 deg C (winter) and it is covered by glaciers. It was discovered by explorer Caption James Ross in 1841 and climbed 1908 by members of Ernest Shackleton's expedition. Since then it was visited only very rarely in the following 100 years.
