List of mountain peaks of Washington explained
This article comprises three sortable tables of major mountain peaks[1] of the U.S. State of Washington.
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.[2] [3] 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.[4] [3] The second table below ranks the 50 most prominent summits of Washington.
- The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.[5] The third table below ranks the 25 most isolated major summits of Washington.
__TOC__
Highest major summits
Of the major summits of the State of Washington, Mount Rainier exceeds 4000m (13,000feet) elevation, four peaks exceed 3000m (10,000feet) elevation, and 97 peaks exceed 2000m (7,000feet) elevation.
Most prominent summits
Of the most prominent summits of the State of Washington, Mount Rainier exceeds 4000m (13,000feet) of topographic prominence, five peaks exceed 2000m (7,000feet), seven peaks are ultra-prominent summits with more than 1500m (4,900feet) of topographic prominence, and 40 peaks exceed 1000m (3,000feet) of topographic prominence.
Most isolated major summits
Of the major summits of the State of Washington, Mount Rainier exceeds 1000km (1,000miles) of topographic isolation, three peaks exceed 100km (100miles), and 16 exceed 40km (30miles) of topographic isolation.

Notes and References
- This article defines a significant summit as a summit with at least 100m (300feet) of topographic prominence, and a major summit as a summit with at least 500m (1,600feet) of topographic prominence. All summits in this article have at least 500 meters of topographic prominence. An ultra-prominent summit is a summit with at least 1500m (4,900feet) of topographic prominence.
- All elevations in this article include an elevation adjustment from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88). For further information, please see this United States National Geodetic Survey note.
- If the elevation or prominence of a summit is calculated as a range of values, the arithmetic mean is shown.
- The topographic prominence of a summit is the topographic elevation difference between the summit and its highest or key col to a higher summit. The summit may be near its key col or quite far away. The key col for Denali in Alaska is the Isthmus of Rivas in Nicaragua, 7642km (4,749miles) away.
- The topographic isolation of a summit is the great-circle distance to its nearest point of equal elevation.
