Waterbury, Vermont. "In the southwest corner of the township, the passage of Onion river through a considerable hill, is considered a curiosity. The stream has here worn a channel through the rocks, which in times past, undoubtedly, formed a cataract below of no ordinary height, and a considerable lake above. The chasm is at present about one hundred feet wide, and nearly as deep. On one side the rocks are nearly perpendicular, some of which have fallen across the bed of the stream, in such a manner as to form a bridge, passable, however, only at low water. On the same side the rocks which appear to have been loosened and moved by the undermining of the water, have again rested, and become fixed in such a posture as to form several caverns or caves, some of which have the appearance of rooms fitted for the convenience of man. Several musket balls and flints were found in the extreme part of the cavern, a few years since, with the appearance of having lain there many years, which makes it evident that it was known to the early hunters." I did find a State Park at Waterbury. On the google intro, it mentioned there being a large cavern but on the site for the park, no mention at all. Use the State Park link to find all the state parks in Vermont. There are some very beautiful ones.
