Dhaulagiri, Winter Ascent. Jerzy Kukuczka and Leszek Czok reached the summit of Dhaulagiri by the north face on the 1984-5 winter season, but Czok got frostbitten toes as the result of a bivouac made on the night after reaching the summit when they could not find the route to camp in the dark. This was Kukuczka’s seventh 8000er. The entire team used no artificial oxygen. The Polish expedition leader was Adam Bilczewski.
