List of Ultras of Greenland
(詳細はultra prominent mountain peaks on the Island of Greenland and the surrounding islands of Kalaallit Nunaat. Each of these summits has a topographic prominence of at least 1500 meters (4921.3 feet).
Topographic elevation is the vertical distance above the reference geoid, a precise mathematical model of the Earth's sea level as an equipotential gravitational surface. Topographic prominence is the elevation difference between the summit and the highest or key col to a higher summit. Topographic isolation is the minimum great circle distance to a point of higher 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 (1640.4 feet) of topographic prominence. An ultra-prominent summit is a summit with at least 1500 meters (4921.3 feet) of topographic prominence.
