The following sortable table comprises the 209 most topographically isolated mountain peaks of the United States of America (including its territories) with at least 500 meters (1640 feet) of topographic prominence.[1][a]
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][3]
- The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.[5]
In the United States, only Denali exceeds 4000 kilometers (2485 miles) of topographic isolation. 3 summits exceed 2000 kilometers (1243 miles), 8 exceed 1000 kilometers (621.4 miles), 13 exceed 500 kilometers (310.7 miles), 47 exceed 200 kilometers (124.3 miles), 113 exceed 100 kilometers (62.14 miles), and 214 major summits exceed 50 kilometers (31.07 miles) of topographic isolation.
- ^ 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.
