History

Saunders Island was discovered in 1775 by Captain James Cook, who named it for Sir Charles Saunders, First Lord of the Admiralty.[1] It was charted in greater detail by Bellingshausen in 1819,[2] and in 1930 by DI personnel aboard Discovery II. The island was surveyed in 1964 by HMS Protector after whose captain, Captain Martin S. Ollivant, the westernmost point, Ollivant Point, is named. Shackleton sometimes misspells the island's name as "Sanders Island" in his book South.

Volcano

Main article: Mount Michael

Mount Michael is known to have erupted explosively in 1819, and has erupted repeatedly since 2000, most recently in 2005. The 700 m (2,297 ft) diameter summit crater contains a persistent lava lake, one of only eight in the world.[3][4][5]

The area is often cloudy, and a seemingly constant volcanic plume conceals the lake most of the time. Fortunately, the team collected enough shots of the lake from 2003 to 2018 that clearly showed a crater floor containing a superheated lake 295 to 705 feet across. The lava is also 1,812 to 2,334 degrees Fahrenheit, with the higher end of that range about as hot as lava on Earth seems to get.
