The following sortable table comprises the 477 mountain peaks of the United States with at least of topographic elevation and at least of topographic prominence. 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. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. In the United States, only Denali exceeds elevation. Four major summits exceed , nine exceed , 104 exceed , 246 exceed , and the following 477 major summits exceed elevation. Major 3000-meter summits A total of 477 mountain summits in the United States meet both criteria for the definition of "major summit" used here: at least of topographic elevation and at least of topographic prominence. Of these 477 summits, 117 are located in Colorado, 67 in Alaska, 51 in California, 43 in Wyoming, 42 in Montana, 40 in Utah, 38 in Nevada, 36 in Idaho, 26 in New Mexico, five in Arizona, five in Oregon, four in Washington, and three in Hawaii. Five of these summits are located on the international border between Alaska and the Yukon, and three are located on the international border between Alaska and British Columbia. The ten highest major summits of the United States are all located in Alaska. The northernmost summit with at least 3000 metres elevation and 500 metres prominence is Hess Mountain in central Alaska; the southernmost is Mauna Loa on the Island of Hawaii; the westernmost is Haleakalā on the Island of Maui; and the easternmost is East Spanish Peak in south-central Colorado. In the contiguous United States (i.e. excluding Alaska and Hawaii), the northernmost, southernmost, westernmost, and easternmost major summits are Kintla Peak in Montana, Mount Graham in Arizona, Mount Shasta in California, and East Spanish Peak in Colorado, respectively.
