Excerpt from Search Polar Basin. And there is Amundsen's own word for it that Ellsworth's participation in the two Arctic Expeditions of 1925 and 1926 was an essential factor to their success. The amundsen-ellsworth Expedition of 1925 reached latitude 87 Degrees 44' North. It explored square miles of hitherto unknown area, it took soundings which showed depths of the Polar Basin at that latitude to be feet, which fact pre cluded the possibility of land on the Europe side of the Pole, and its observations showed that meteoro logical conditions offered no obstacles to aerial ex ploration of Arctic regions. The amundsen-ellsworth-nobile Transpolar Flight from Spitzbergen to Alaska, in 1926, across the North Pole and across the Ice Pole, spanned the largest remaining terrestrial blind spot, and proved that no continental mass of land lies between the North Pole and Alaska.
