Seven (+1) Summits
The Seven Summits of mountaineering are the tallest peaks on each continent. Because mountaineers cannot agree on whether to include the highest peak in Australia and Oceania as on the Australian mainland or the continent's island groups, the Seven Summits often includes eight mountains! From top left, in descending order of elevation: Mount Everest, Nepal and China (Asia); Aconagua, Argentina (South America); Denali, United States (North America); Kilimanjaro, Tanzania (Africa); Mount Elbrus, Russia (Europe); Mount Vinson, Antarctica; Puncak Jaya, Indonesia (Australia and Oceania); and Mount Kosciuszko, Australia.
