Seven summits
The Seven Summits are the highest mountains of each of the seven continents. Summiting all of them is regarded as a mountaineering challenge, first achieved on April 30, 1985 by Richard Bass.
The Seven Summits are composed of each of the highest mountain peaks of each of the seven continents. Different lists include slight variations, but generally the same core is maintained. The seven summits depend on the definition used for a continent — in particular the location of the border of that continent. This results in two points of variation: the first is Mont Blanc versus Mount Elbrus for the continent of Europe; and the second depends on whether one includes all of Oceania or only mainland Australia as the continent, which results in either Puncak Jaya (also known as "Carstensz Pyramid") or Mount Kosciuszko, respectively.
This creates several possible versions of the seven summits:
The concept Bass and his climbing partner Frank Wells were pursuing was to be the first to stand atop the highest mountain on each continent. They pursued this goal as they defined it, climbing Aconcagua for South America, Denali (formerly McKinley) for North America, Kilimanjaro for Africa, Elbrus for Europe, Vinson for Antarctica, Kosciuszko for Australia, and finally Everest for Asia.
Using the largest tectonic plates, Europe and Asia could be grouped as Eurasia, and the very large Pacific plate with Mauna Kea. Note that Carstensz/Puncak is actually on the Maoke Plate, which is usually grouped with the larger Australian plate. If not, then Mount Kosciuszko would likely revert to being the highest of that plate.
