Earth:List of the ultra-prominent summits of Alaska
The following sortable table comprises the 65 ultra-prominent summits of the United States State of Alaska. Each of these peaks has at least 1500 meters (4921 feet) of topographic prominence.
Topographic elevation is the vertical distance above the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface. The topographic prominence of a summit is the elevation difference between that summit and the highest or key col to a higher summit. The topographic isolation of a summit is the minimum great-circle distance to a point of equal elevation.
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. An ultra-prominent summit is a summit with at least 1500 meters (4921 feet) of topographic prominence. There are 126 ultra-prominent summits in the United States.
If an elevation or prominence is calculated as a range of values, the arithmetic mean is shown.
