It’s pretty unique in VT. What are the other gaps/notches? Hazel’s Notch, Appalachian Gap, Lincoln Gap, Middlebury Gap and Brandon Gap are the ones I can think of and none of them are quite the same.
Oddly, the closest thing I can think of is a valley location, the Williamstown Gulf. The Second Branch of the White River cuts through the hills and Rt. 14 runs along side it. At its narrowest, there is barely enough room for the road and the river. The sides are really steep and there are cliffs. Rt.14 gets closed there once in awhile from ice/snow slides. The only picture I could find online is an old postcard that doesn’t really do it justice.
