The Vestfold Hills are rounded, rocky, coastal hills, 411 square kilometres (159 sq mi) in extent, on the north side of Sorsdal Glacier on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica. The hills are subdivided by three west-trending peninsulas bounded by narrow fjords. Most of the hills range between 30 and 90 metres (98 and 300 ft) in height, with the highest summit reaching nearly 160 metres (520 ft).


The Vestfold Hills are largely snow and ice-free and are thus classified as an Antarctic oasis. They contain a great variety of lake systems with over 300 lakes and ponds[1] including what is possibly the largest concentration of meromictic (stratified) lakes in the world.[2] This region contains 37 permanently stratified water bodies,[3] including six marine basins and seven seasonally isolated marine basins (SIMBs). These stratified basins also have great variety. They range in salinity from 4 g L−1 to 235 g L−1, in temperature from −14 to 24 °C (6.8 to 75 °F), in depth from 5 to 110 metres (16 to 361 ft), in area from 3.6 to 146 hectares (8.9 to 360.8 acres) and surface level from 30 metres (98 ft) below to 29 metres (95 ft) above sea level.[2] The region contains a large lake, Lake Burton, as well as the smaller Krok Lake and Camp Lake.

History and naming[edit]

The Vestfold Hills were discovered and a landing was made in the northern portion on February 20, 1935, by Captain Klarius Mikkelsen together with his wife and seven crew members (including the ship's dentist, Lief Sørsdal) of the Norwegian whaling ship "Thorshavn" sent out by Lars Christensen. Mrs Caroline Mikkelsen thereby became the first woman to set foot on the Antarctic continent.[citation needed]

The Vestfold Hills are named after Vestfold, a county in Norway where Sandefjord, headquarters of the whaling industry, is located. This hill area and its off-lying islands were mapped from air photos taken by the Lars Christensen Expedition (1936–37). Further brief landings were made by Lincoln Ellsworth and several claims made by Hubert Wilkins in 1939. and the area was photographed from the air by USN Operation Highjump (1946–47). Landings were made and exploration carried out in 1954 and 1955 by ANARE (Australian National Antarctic Research Expeditions) led by Phillip Law. Davis Station was established by ANARE in January 1957.[citation needed]
