I think people should really stop naming falls "buttermilk".
There are a whole bunch listed on this website:

The one my near Finger Lakes National Forest that my professor was talking about was Taughannock

Which could be the largest single drop.
Wikipedia doesn't have anything nice to say about inspiration falls, they say it's only a trickle (less than 1 foot wide) when it is flowing, and is just a wet stain on the wall for most months out of the year, they also mention "(Taughannock Falls, 100 miles east of Letchworth in Trumansburg is generally recognized as the highest waterfall in New York as well as in the entire Northeastern United States)."

I dunno, if you did all that measuring you should probably get that work published or something so that it is recognized. Is there like a national waterfall measuring committee or something? If you're doing all the dangerous hard work someone should at least put you down as a footnote in a book right?
Also what is your method for measuring these waterfalls? I'd imagine using some trigonometry would probably be the most practical solution. Like if you knew how far away from the base of the waterfall you were, and the angle to the top of the falls, you could use the tangent to calculate the height. I'd imagine this could be done without foliage on the trees from a distance, and you wouldn't have to cause rock slides or get attacked by bobcats.
