Perhaps they are alluding to the abandoned hard rock mines in Morris,
Passaic, Warren and Sussex counties?? I have traveled around a bit and am
aware of no large caverns beneath my beloved NJ. I am eager to learn more,
though...

I just saw Garden State(a movie worth seeing for this), and this film of
an
underground canyon in New Jersey, that was uncovered, when someone was
trying to building a shopping mall. I guess they had to stop. Mother
Nature stopped them cold. Does anyone know anything about this. It's kind
of a gardening question.
