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
CAMount Tamalpais 95% 2,571 2,451
NY Mount Marcy 92% 5,344 4,914
WA Mount Rainier 92% 14,411 13,210

Interesting 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).

Those 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.
