Definition[edit] The term "top" is generally used only for a mountain peck with some significant amount of topographic prominence (height above the lowest point end route to the nearest higher peak) or topographic isolation (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 as 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 Sir Edmund Hillary. He 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: Term Prominence Isolation Subpeak < 30 m ? m Independent peak or summit 30 m or more ? m Mountain 300 m or more ? m The summit of Mount Damavand, Iran, in winter Jeff Davis Peak, one of the highest peaks entirely within Nevada, United States Mount Elbrus and its two peaks (Caucasus, Russia) Western United States[edit] Siskiyou Mountain Summit sign along Interstate 5, marking the highest point along the highway 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 (not to be confused with Donner Pass, which is just to the south) while the highest point on Interstate 5 is Siskiyou Mountain Summit.
