List of the most prominent summits of North America
The following sortable table lists the 200 most topographically prominent mountain peaks of greater North America.
This article defines greater North America as the portion of the continental landmass of the Americas extending northward from Panama plus the islands surrounding that landmass. This article defines the islands of North America to include the coastal islands of North America, the islands of the Caribbean Sea, the Lucayan Archipelago, the Bermuda Islands, the Islands of Greenland (Kalaallit Nunaat), the islands of Northern Canada, the islands of Alaska, and the islands of the northeastern Pacific Ocean. The Hawaiian Islands are not included because they are considered part of Oceania.
Topographic elevation is the vertical distance above the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface. The topographic prominence of a summit is the elevation difference between that summit and the highest or key col to a higher summit. The topographic isolation of a summit is the minimum great-circle distance to a point of equal elevation.
This article defines a significant summit as a summit with at least of topographic prominence, and a major summit as a summit with at least of topographic prominence. An ultra-prominent summit is a summit with at least of topographic prominence. There are 354 ultra-prominent summits in greater North America.
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 ).
Of these 200 most prominent summits, 81 are located in the United States, 74 in Canada, 16 in Mexico, 16 in Greenland, 7 in Guatemala, 2 in Costa Rica, 2 in the Dominican Republic, 2 in Haiti, 2 in Honduras, and one each in Jamaica, Cuba, El Salvador, and Panama. Six of these peaks lie on an international border.
In North America, only Denali exceeds ) of topographic prominence, and Mount Logan exceeds of prominence. Four peaks exceed , 17 exceed , 101 exceed , and of topographic prominence.
