I hit up this spot a couple of times a year when I am back home in VT. It is actually on the New York side of Lake Champlain. It is most easily accessible by boat. There are hiking trails to the spot but I have only accessed them via boat. From the Vermont side it is almost directly across the lake from Basin Harbor Club in Ferrisburgh, VT. The club has kayak rentals and even does boat trips to the spot for a fee. I’m not sure the exact height of the top. I have heard anywhere from 80-90ft and the water level rises and falls probably 10 feet throughout the year. As you can see in the pics you can jump from pretty much any height you want from 1 foot all the way up to the top. The water is over 60 feet deep and it’s a sheer cliff so there are no under water ledges or anything to worry about.
