This article lists the highest mountains of the world and some of their prominent subpeaks.
Eight-Thousander (8000 meter peaks)
The fourteen independent highest mountains on Earth
The eight-thousanders are the fourteen independent mountains on Earth that are more than 8,000 metres above sea level. They are all located in the Himalayan and Karakoram mountain ranges in Asia. The generally accepted list of fourteen eight-thousanders is obtained if one uses a topographic prominence cutoff between 200 and 500 metres.
Seven-Thousander (7000 meter peaks)
Jill Neate's great book "High Asia: An Illustrated History of the 7,000 Metre Peaks" provides a lot of information on each of the over 400 known peaks between 7000 and 8000 metres. It contains detailed summaries of their location, access and routes, together with descriptions of their individual histories of exploration and ascents.
Six-Thousander (6000 meter peaks)
There are only two mountain ranges outside the Asian continent where peaks over 6000 m are located: The Alaska Range with its highest peak Mount McKinley (6193 m) and the Andes with its highest peak Aconcagua (6962 m). While Mount McKinley is the only peak over 6000 m on the North American contient, there are 102 peaks over 6000 m on the South American continent. They all have a topographic prominence of at least 400 m. By contrast the asian continent counts a few thousand peaks over 6000 m.
Five-Thousander (5000 meter peaks)
If the Caucasian mountains belong to Europe there are 5 continents with peaks over 5000 m: The Asian continent, North and South America, Africa and Europe. While the 5000 m peaks in Asia - particularly Himalaya and Karakorum - reache uncountable numbers, other regions with 5000 m peaks keep manageable. The Andes count more than 800 peaks over 5000 m, Alaska and Canada count about 30 or 40, Africa about 10, the Caucasian mountains about 20 and the Elbruz mountain range counts only one peak over 5000 m.
The following list describes mountain ranges where the number of 5000 m peaks keeps manageable and where the highest peak is between 5000 m and 6000 m. Therefore the Alaska Range, the Andes and the ranges close to the Himalaya are not itemized. Despite this assumptions there remain still 11 independent ranges with a main peak higher than 5000 m.
Four-Thousander (4000 meter peaks)
All continents (Asia, North and South America, Africa, Europe, the Ocean Islands and the Antarctica) have mountain ranges with peaks over 4000 m except Australia. While most of this ranges reach uncountable numbers of 4000 m peaks there are some well known 4000 m peak lists like the Colorado fourteeners of the USA or the 4000 m peak list of the European Alps.
Three-Thousander (3000 meter peaks)
Mountains ranges with 3000 m peaks are located on every continent (Asia, North and South America, Africa, Europe, the Ocean Islands and the Antarctica) except Australia. Most of them reach uncountable numbers of peaks.
Two-Thousander (2000 meter peaks)
The Australian continent is the lowest-lying continent on Earth with Mount Kosciusko (2228 m) as its highest point. All peaks over 2000 m are located in the Great Dividing Range. Most of the 2000 m peak lists are mountain range specific or country specific. One example is the Norway peak list containing 291 peaks with an elevation of 2000 m above sea level and a topographic prominence of more than 10 meters. Increasing the topographic prominence to more than 50 meters shrinks the list to 186 peaks. So everything is a question of definition, but the highest point of Norway remains Galdhøpiggen with an elevation of 2469 m.
