Was reading through some geologic stuff and found this:
Because subduction of slabs to depth is necessary to drive subduction zone volcanism (through the destabilization and dewatering of minerals and the resultant flux melting of the mantle wedge), flat-slab subduction can be invoked to explain volcanic gaps.
First thoughts through my mind was Pine Mountain and then Mammoth Cave. Volcanic gaps would be a good explanation for both.
