This article comprises three sortable tables of major mountain peaksThis 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. All summits in this article have at least 500 meters of topographic prominence. An ultra-prominent summit is a summit with at least of topographic prominence. of the U.S. State of Idaho.

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.All elevations in this article 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 first table below ranks the 40 highest major summits of Idaho by elevation. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.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, away. The second table below ranks the 40 most prominent summits of Idaho. The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.The topographic isolation of a summit is the great-circle distance to its nearest point of equal elevation. The third table below ranks the 40 most isolated major summits of Idaho. __TOC__
