Having skied 1,117 miles across the Antarctic, Ryan Waters and Cecilie Skog have proven beyond all doubt that Antarctic expeditions are far from stagnant. They have succeeded in completing the longest fully unsupported Antarctic journey ever, having skied from Berkner Island on the Weddell Sea to where the rocky continent meets the Ross Ice Shelf at the Axel Heiberg glacier. They appear to be in reasonable physical condition.
This marks an important landmark in polar expeditions in the same league as the 2000 Arctic Ocean unsupported crossing (Gjeldnes and Larsen) and Matvey Shparo and Boris Smolin's North Pole winter success in 2008.
This also confirms that distances in excess of 1,000 miles are possible in the unsupported (no resupply or power support) polar world. Only two have done so previously, the 2000 Arctic Ocean crossing (1,071 miles) and the Tiso Trans Greenland (1,374 miles).
The concept of an unsupported full crossing of the Antarctic, for example from Berkner Island to McMurdo Bay via the South Pole, is now entirely plausible.
