List of extreme summits of North America explained

This article comprises four sortable tables of mountain summits of greater North America^[1] that are the higher than any other point north or south of their latitude or east or west their longitude in North America.

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.^[2] ^[3]
The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.^[4] ^[5] ^[3]
The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.^[6]

Notes and References

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.
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.
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, 7642km (4,749miles) away.
This article defines a significant summit as a summit with at least 100m (300feet) of topographic prominence, and a major summit as a summit with at least 500m (1,600feet) 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 1500m (4,900feet) of topographic prominence.
The topographic isolation of a summit is the great-circle distance to its nearest point of equal elevation.
