Highest major summits

Of the 100 highest major summits of the United States, only Denali exceeds elevation, four peaks exceed , and all 100 peaks exceed elevation. Of these 100 summits, 53 are located in Colorado, 23 in Alaska, 14 in California, five in Wyoming, two in Hawaii, and one each in Washington, Utah, and New Mexico. Five of these summits are located on the international border between Alaska and Yukon, and one is located on the international border between Alaska and British Columbia. The ten highest major summits of the United States are all located in Alaska.

Most prominent summits

Of the 50 most prominent summits of the United States, only Denali exceeds of topographic prominence, three peaks exceed , ten peaks exceed , 45 peaks exceed , and all 50 peaks exceed of topographic prominence. All of these peaks are ultra-prominent summits. Of these 50 peaks, 27 are located in Alaska, five in Washington, five in California, three in Hawaii, three in Wyoming, two in Nevada, two in Oregon, and one each in Colorado, Utah, and Arizona. Three of these summits lie on the international border between Alaska and Yukon, and one lies on the international border between Alaska and British Columbia.
