What is the 90% dominance list?
Dominance is the topographical prominence of a mountain divided by its summit elevation; in other words, the prominence/elevation ratio. For a definition of prominence theory, see the excellent, detailed
Peaklist page. This list includes the 13 peaks in the contiguous United States with a prominence/elevation ratio of 90% or greater. The top 3 peaks on this list, all island highpoints, automatically have 100% dominance, and so are ranked by elevation. The rest of the mountains are ranked by dominance from greatest to least. So, without further ado, the U.S. 90% Dominance List.
(It should be noted that there are plenty of peaks in Alaska and Hawaii that would be on this list were those states included.)
The U.S. 90% Dominance List
Data taken from the
Peaklist page detailing dominance (see 5.5.) Peaks on this list are at least 2000' in height to rule out less significant peaks.
U.S. State | Name | Dom. (%) | Elev. (Ft.) | Prom. (Ft.) |
CA | Devils Peak | 100% | 2,470 | 2,470 |
WA | Mount Constitution | 100% | 2,407 | 2,407 |
CA | Mount Orizaba | 100% | 2,097 | 2,097 |
WA | Mount Olympus | 98% | 7,969 | 7,829 |
NH | Mount Washington | 98% | 6,288 | 6,148 |
CA | South Butte | 97% | 2,117 | 2,047 |
CA | Mount Tamalpais | 95% | 2,571 | 2,451 |
NY | Mount Marcy | 92% | 5,344 | 4,914 |
WA | Mount Rainier | 92% | 14,411 | 13,210 |
WA | Round Mountain | 91% | 5,320 | 4,780 |
NC | Mount Mitchell | 91% | 6,684 | 6,089 |
CA | Loma Prieta | 90% | 3,786 | 3,426 |
WA | Anderson Mountain | 90% | 3,364 | 3,034 |

LimitationsInteresting list. It should probably be stated that this is limited to mountains with 2000 feet of prominence, with a P. Without that limitation, the dominance, with a D, list would be an endless list of offshore island highpoints. Also, this is not a U.S. list--it's a list for the contiguous U.S., excluding Alaska and Hawaii. I believe Hawaii would add 6 to the list and Alaska and Alaska several dozen (there are a lot of P2000 island highpoints in Alaska, and then there'd be a number of P2000 mainland peaks in the 90s for dominance).

Re: LimitationsThose are all good points. I think I'll rename the page, because adding Alaska, particularly the southeastern islands and the Aleutians, would be a real pain, as would adding all sub-2000' peaks. Thanks for your contribution.
