Taken from source page:

"This mechanical drawing of Saint Paul Street and the eastern wall of High Falls gorge shows what’s behind the mysterious door. It’s actually a Saint Paul Street drainage tunnel!"

"The High Falls “mystery door” was, in fact, part of a storm water collection system for the Upper Falls area. It was designed by The Sear-Brown Group, Inc., a local design & engineering firm (now Stantec) in the 1970’s. It was soon abandoned however, when it was replaced by the major sewer tunnels that were built by Monroe County’s Pure Waters program in the 1980’s."

Has anyone seen what remains of the vortex?

Also Can some one make a post for the Rico tunnel/cave if there is not one already? It is apparently used for overflow.
