Polar Plateau

 

the level surface of the ice sheet at the center of which the south pole is located. Elevation varies between 2,500 and 3,000 m. The thickness of the ice sheet ranges from 1,500 to 3,000 m. The average annual temperature is approximately – 50° C. In January 1909 members of the British expedition of E. Shackleton became the first people to reach the Polar Plateau. In late 1911 and early 1912 the Norwegian expedition of R. Amundsen and the British expedition of R. Scott reached the central part of the Polar Plateau. The American Amundsen-Scott scientific station began operating at the south pole in January 1957.

Over the next few days the team sets out on multiple exploratory climbing trips that vary from hard technical ascents to magnificent ridge traverses with views over the Ronne Ice Shelf and Polar Plateau. We attempt steep ice and snow couloirs, classic ridge traverses, icy crests, rock pyramids, hidden valleys, and finally unclimbed peaks!
To complete their remarkable feat they started on the edge of the Ross Ice Shelf on November 20 and climbed up the Transantarctic Mountains, via the Leverett Glacier, to reach the polar plateau.
In conjunction with the anomalously high pressures, Amundsen and his crew experienced temperatures that peaked above -16[degrees]C on the polar plateau on 6 December 1911, which is extremely warm for this region.

In the first week of November, the party landed on the edge of the Polar Plateau at the head of the Mill Glacier tributary to the Beardmore.
She said: "It's hard to predict because he might well use the tactic of putting in a 24-hour ski on the last day or, once he hits the polar plateau at 89 degrees, he might make a last big push for the last 100km.
Now the glacier stage is over, Maria has set her mind to cycling across more than 310 miles of polar plateau in the face of white-outs and bitterly cold conditions.
I camped in the desert in Namibia and on the polar plateau, twenty kilometers from the South Pole.
In 1908, Shackleton and three companions reached a new farthest south latitude, discovered the Beardmore Glacier and became the first people to travel on the South Polar Plateau. But they failed to make it to the South Pole proper.
The unimaginative simply hoped to find ice-free areas inland on the polar plateau; the imaginative took their cue from Macrobius.
The arrival at the Pole, 90 degrees South latitude, was the capstone of months of preparation, training and conditioning; travel to an Antarctic base station; and a flight to a location at 89 degrees South; to launch the overland trek across the polar plateau known as "The Last Degree." It is a 111-km journey on skis, over a number of days -- achieving 20 km on any day is quite remarkable -- with painful progress decided by the whims of the weather, which had the team pinned down in their tent shelters 41 km short of their goal, for several days.
