Definition


The term "top" is generally used only for a mountain peak that is located some distance from the nearest point of higher elevation. For example, a big massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered subsummits (or subpeaks) of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top.
Summit may also refer to the highest point along a line, trail, or route.


The highest summit in the world is Everest with height of 8844.43 m above sea level (29,029 ft). The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary. They reached the mountain`s peak in 1953.[1][2] The UIAA definition is that a summit is independent if it has a prominence of 30 metres (98 ft) or more; it is a mountain if it has a prominence of at least 300 metres (980 ft). This can be summarised as follows:

In many parts of the western United States, the term summit refers to the highest point along a road, highway, or railroad. For example, the highest point along Interstate 80 in California is referred to as Donner Summit and the highest point on Interstate 5 is Siskiyou Mountain Summit.



Summit climbing equipment






A summit climbing differs from the common mountaineering. Summit expedition requires: 1+ year of training, a good physical shape, and a special gear. Although a huge part of climber’s stuff can be left and taken at the base camps or given to porters, there is a long list of personal equipment. In addition to common mountaineers’ gear, Summit climbers need to take Diamox (anti-altitude sickness medication), masks, and bottles of oxygen. There are also special requirements for crampons, ice axe, rappel device, clothing, etc.
