US States With Ultraprominent Mountains

List the US states with Ultraprominent mountains/"Ultras", or mountains with over 1500 m/~4920 ft of topographic prominence
Topographic prominence is not elevation, it is a measurement of the minimum elevation you must drop off a summit before climbing to a higher mountain. A nearly flat rise at high elevation would have minimal prominence, while a rugged low elevation point with few connecting ridgelines would have a higher prominence
As the most prominent point in New York is 1 meter short of being an Ultra, it is given.

Alaska has a ton of Ultras because it has tons of volcanoes and tons of mountainous islands. With prominence rules, every island with an elevation above 1500 meters automatically contains at least one Ultra, as the prominence of an island high point is identical to the elevation.

Volcanoes tend to have high prominences compared to other mountains as they tend to form isolated conical peaks rather than long ridges. A line of gigantic isolated mountains will have a pretty good chance of containing multiple ultras, while a single long ridgeline would probably only have one ultra at the high point of the ridge.

Regarding New York, 1499 m of prominence is close enough that it could actually be an Ultra. Would require either the elevation of Mount Marcy to be measured incorrectly, or the elevation of the low point to a higher peak, likely the Mohawk River Valley, to be off. Either way, when it is literally just a foot or two difference, that is usually within the margin of error.
