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. The [|first table] below ranks the 100 highest major summits of Washington by elevation.
- The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. The [|second table] below ranks the 50 most prominent summits of Washington.
- The topographic isolation of a summit measures how far the summit lies from its nearest point of equal elevation. The [|third table] below ranks the 25 most isolated major summits of Washington.
