The following sortable table comprises the 230 mountain peaks of greater North America[1] with at least 100 kilometers (62.14 miles) of topographic isolation and at least 500 meters (1640 feet) of topographic prominence.[2]
The summit of a mountain or hill may be measured in three principal ways:
- The topographic elevation of a summit measures the height of the summit above a geodetic sea level.[3][4]
- The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.[5][4]
- The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.[6]
Denali is one of only three summits on Earth with more than 6000 kilometers (3728 miles) of topographic isolation. Four major summits of greater North America exceed 2000 kilometers (1243 miles), eight exceed 1000 kilometers (621.4 miles), 35 exceed 500 kilometers (310.7 miles), 107 exceed 200 kilometers (124.3 miles), the following 230 major summits exceed 100 kilometers (62.14 miles), and 413 exceed 50 kilometers (31.07 miles) of topographic isolation.
- ^ This article defines greater North America as the portion of the continental landmass of the Americas extending westward and northward from the Isthmus of Panama plus the ocean islands surrounding that landmass. This article defines the ocean islands of greater North America to include the coastal islands of North America, the islands of the Caribbean Sea, the Lucayan Archipelago, the islands of Greenland (Kalaallit Nunaat), the islands of Canada, and the islands of Alaska. The Hawaiian Islands are not included because they are considered part of Oceania.
- ^ This article defines a significant summit as a summit with at least 100 meters (328.1 feet) of topographic prominence, and a major summit as a summit with at least 500 meters (1640 feet) of topographic prominence. All summits in this article have at least 500 meters of topographic prominence. An ultra-prominent summit is a summit with at least 1500 meters (4921 feet) of topographic prominence.
- ^ All elevations in the 48 states of the contiguous United States include an elevation adjustment from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88). For further information, please see this United States National Geodetic Survey note.
- ^ a b If the elevation or prominence of a summit is calculated as a range of values, the arithmetic mean is shown.
- ^ The topographic prominence of a summit is the topographic elevation difference between the summit and its highest or key col to a higher summit. The summit may be near its key col or quite far away. The key col for Denali in Alaska is the Isthmus of Rivas in Nicaragua, 7642 kilometers (4749 miles) away.
- ^ The topographic isolation of a summit is the great-circle distance to its nearest point of equal elevation.
