Ausable Chasm is located in the Adirondacks of New York State. US Route 9 is the main road that crosses the chasm, but formerly the road used was located slightly east of US 9. The bridge over this road, Old State Road, is still present, but closed to traffic.
From the south side of the old bridge, one can see stone ruins along the chasm. I am unsure of the history of these ruins. If you know anything, please contact me!
