Traverse of Antarctica via the South Pole, 1990-1. Four Norwegians, Ralph Hoibakk, leader, Herman Mehrem, Simen Mordre and Sjur Mordre, traversed the Antarctic Continent, setting out from the Ronne Ice Shelf in October, 1990, with dogs but without any motorized assistance. On the way to the South Pole, which they reached on December 14,1990, they did have several supply depots. They continued on to McMurdo without depots. The 3000-kilometer traverse was accomplished in 120 days.
