Geology:

The expedition mapped the Brown Hills region - this taking less time than allowed for as the geology was less complex than expected. As the party could not sledge across to Darwin Mountains or Tentacle Ridge, air support was asked for to allow the mapping of Darwin Mountains.

Due to the short length of time required in the Darwin Region it was decided to map Taylor Valley as well this season. As well as dealing with Taylor Valley itself the expedition spent a few days at Marble Point, a few miles north east of Taylor Valley. This work completes the detailed coverage by V.U.W.'s Antarctic Expeditions 1, 2, 3 and 4 in the "McMurdo Oases" - a largely ice-free region stretching from the Koettlitz névé north to McKay Glacier, an area of about 3,000 sq. miles.
