The following sortable table comprises the 200 most topographically prominent mountain peaks of the United States of America. 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. [1] [2]
Differences in roughness (topographic relief) result from a variety of processes acting on the underlying rock. The plate tectonic history of a region strongly influences the rock type and structure exposed at the surface, but differing rates of erosion that accompany changing climates can also have profound impacts on the land.

The topographic elevation of a summit measures the height of the tip of a mountain above a geodetic sea level. [b] [c] The first table below ranks the 100 highest major summits of the United States by elevation. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.
The United States shares land borders with Canada and Mexico and maritime borders with Russia, Cuba, the Bahamas, and many other countries, mainly in the Caribbean [note 2] in addition to Canada and Mexico. The northern border of the United States with Canada is the world's longest bi-national land border.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
The term "topographic surveys" appears to be American in origin. The earliest detailed surveys in the United States were made by the "Topographical Bureau of the Army", formed during the War of 1812, [7] which became the Corps of Topographical Engineers in 1838. [8]
The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. The lowest point on that route is the col. For full definitions and explanations of topographic prominence, key col, and parent, see topographic prominence. In particular, the different definitions ...
