Mountains Above The Treeline in the Northeast US

Alpine vegetation is extremely rare in the eastern US, limited to a few disjunct patches. List all the mountains which appear to contain alpine vegetation.
Mountain here is defined as a peak with over 160 feet of prominence above the surrounding ridgeline, similar to the AMC definition. Where there is a well known lower subpeak above a treeline but the main peak is still forested, the main peak is included with the subpeak in parentheses
Appalachian balds in the southern Appalachians are not included as they are mechanically different from true treelines elsewhere.
This is based on a mix of arbitrary decisions with Google Maps and the locations listed in the Eastern Alpine Guide, which is basically the only book really dedicated to this topic. Did a little spot checking with Peakbagger to confirm some of these.
Includes some locations where treelines were lowered due to fires, determining if the mountains originally had a treeline before the fire was difficult for me. The treeline height can vary greatly due to exposure.

Very arbitrary in some of these. South Twin, Flume, West Bond in NH might arguably be barely above treeline at their summits, same with Jay Peak in Vermont. There are several points in the Mahoosucs of Maine and NH where there seem to be bogs around the summits of the lower mountains, I ended up deciding that the patch on Success and North Goose Eye were alpine in addition to definite alpine on Sunday River Whitecap and Goose Eye itself, but there are 2-3 other mountains where there is a little bog on the summit I could not determine was tundra or just a wetland that happened to be on the top of a mountain.

Really more of a proof of concept than anything, given how arbitrary it gets when it comes to things like exposed cliff faces or alpine bogs near summits.I could easily drop 20 or so mountains off this list, and I could probably add 20 more marginal examples. Bit arbitrary to leave off balds in the South when I am including mountains which only have a treeline due to fires.

First update. Added Mahoosuc Mountain in the Mahoosucs, North and South Turner in Baxter State Park, Tumbledown and Little Jackson Mountains in the Blue Mountain area. All of these are pretty marginal and may be due to fires or are misidentified bogs, but I decided that they might be worth including. Also on second thought added South Twin, which is definitely tall enough to have a true treeline and appears to have a tiny summit cone with shrub vegetation.

Still of two minds on the following mountains:

Jay Peak in VT.

Whitewall Mountain, Chocorua, Middle Moat, possibly South Moat, Percy Peaks and Kearsarge in NH. All low elevation peaks with exposed summit or flanks, likely due to fire damage.

Rumford Whitecap, Fulling Mill Mountain and Cadillac Mountain* (among other Acadia peaks) in Maine. Possibly a couple other Baxter SP peaks that are rocky near the summit. Probably not true treelines.

Rocky Branch Ridge and Saddleback in New York.

Ended up adding Chocorua as the Eastern Alpine guide mentions that it has a fairly intact alpine ecosystem, even given that it is fire-caused.
