The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. [5] [4] The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. [6] In greater North America, only Denali exceeds 6000 meters (19,685 feet) elevation. Three ...
