In 1985 Richard Bass first postulated and achieved the mountaineering challenge Seven Summits, climbing the highest peaks of each of the seven continents. Messner suggested another list (the Messner or Carstensz list) replacing Mount Kosciuszko with Indonesia's Puncak Jaya, or Carstensz Pyramid (). From a mountaineering point of view the Messner list is the more challenging one. Climbing Carstensz Pyramid has the character of an expedition, whereas the ascent of Kosciuszko is an easy hike. In May 1986 Pat Morrow became the first person to complete the Messner list, followed by Messner himself when he summitted Mount Vinson in December 1986 to become the second.
