First up, a really good one, Barberville Falls. This is on Poestenkill Creek (or just the Poesten Kill, since kill means creek or stream in Dutch) and is ~60 feet or so. Long the scene of high school keg parties and hot summer days crowded with people beating the heat, it's now owned by the Nature Conservancy and access is no longer a sketchy sneak in.
Thing is, I had to reach waaaayyyy back into my film archives to find a picture of this one. Apparently, familiarity breeds contempt and I haven't given this one much photo time compared to smaller waterfalls that are miles further away from home. Oh well, maybe I will get over there some time with good light and do it justice.
New pic I just took a couple hours ago: Here's a google map.
Russell Dunn has this one listed in his Hudson Valley Region Guide on pages 91-93.
