Scott Base stands in the shadow of Mount Erebus, Antarctica’s southernmost active volcano. Mount Erebus was discovered on January 27, 1841 (and observed to be in eruption) by polar explorer Sir James Clark Ross who named it after one of his ships. In Greek mythology Erebus was a primordial god of darkness and the son of Chaos – perhaps Sir Ross had this in mind when he named the volcano.

The first ascent of Mount Erebus was made in 1908 during Shackleton’s British Antarctic (Nimrod) Expedition of 1907-1909. On reaching the summit, the party measured the altitude with a hypsometer - a small cylinder in which distilled water is boiled and the temperature measured (as the temperature at which water boils drops with altitude). Meteorological experiments were carried out and rock samples taken. The ascent took 5 days and on return the 6 men were said to be ‘nearly dead’. This was the first ascent of any peak on Antarctica and was made with improvised equipment such as crampons fashioned out of leather and nails.
Today, Mount Erebus is still a feature of attraction for scientists as the most active volcano in Antarctica. The summit has a permanent magma-filled lake, one of only a few in the world. The volcano produces Erebus crystals, which grow in the magma and are ejected during eruptions. So rare are these crystals they are only found in one other place in the world, a long long way away on Mount Kenya.
