Visit to Lake Bonney
Lake Bonney (77°43′S 162°22′E ) is a saline lake with permanent ice cover at the western end of Taylor Valley in the McMurdo Dry Valleys of Victoria Land, Antarctica.
It is 7 kilometres (4.3 mi) long and up to 900 metres (3,000 ft) wide. A narrow channel only 50 metres (160 ft) wide (Lake Bonney at Narrows) separates the lake into East Lake Bonney (3.32 square kilometres [1.28 sq mi]) and West Lake Bonney (0.99 square kilometres [0.38 sq mi]).
To the north and south of the lake lie peaks that are over 1,500 metres (4,900 ft) above sea level, and the Taylor Glacier is positioned to the west of the lake. It is 130 feet (40 m) deep and is perpetually trapped under 12 to 15 feet (3.7 to 4.6 m) of ice.
It was first visited by the British Antarctic Expedition of 1901-1904. It was named by the Scott expedition of 1910-1913, for Thomas George Bonney, professor of geology at University College London.
Lake Bonney is fed by a number of meltwater streams:
Doran Stream (feeding Priscu Stream)
Priscu Stream (the longest with 3.8 km)
Santa Fe Stream
