List of the most isolated major summits of the United States explained

The following sortable table comprises the 209 most topographically isolated mountain peaks of the United States of America (including its territories) with at least 500m (1,600feet) of topographic prominence.^[1]

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 topographic prominence of a summit is a measure of how high the summit rises above its surroundings.^[4] ^[3]
The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.^[5]

In the United States, only Denali exceeds 4000km (2,000miles) of topographic isolation. 3 summits exceed 2000km (1,000miles), 8 exceed 1000km (1,000miles), 13 exceed 500km (300miles), 47 exceed 200km (100miles), 113 exceed 100km (100miles), and 214 major summits exceed 50km (30miles) of topographic isolation.

Most isolated major summits

See also: List of the major 100-kilometer summits of the United States. The list below contains the 200 most isolated major summits in the 50 states and District of Columbia, plus an additional 9 major isolated summits in the U.S. territories, for a total of 209 summits.

Of these 209 most isolated major summits of the United States, 63 are located in Alaska, 19 in Montana, 16 in California, 14 in Utah, 13 in Nevada, 12 in Colorado, 12 in Arizona, 10 in Wyoming, 7 in Washington, 7 in Oregon, 6 in New Mexico, 5 in the Northern Mariana Islands, 4 in Hawaiʻi, 3 in Idaho, 3 in Texas, 2 in North Carolina, 2 in Maine, 2 in New York, 2 in American Samoa, 2 in Puerto Rico, and one each in New Hampshire, Arkansas, South Dakota, Tennessee, Vermont, Virginia, and West Virginia. Two of these summits lie on the international border between Alaska and British Columbia and one lies on the state border between Tennessee and North Carolina.

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 the 48 states of the contiguous United States 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.
200 in the 50 states and District of Columbia, plus 9 in the U.S. territories
Highest point in the Mariana Islands archipelago and all of Micronesia. Most isolated major mountain in the United States that is not located within a state. The world isolation rank of Agrihan is #34.
