Middlesboro is in Kentucky. We have several cryptoexplosive structures
in the state, the one at Middlesboro is the largest. There are sites
recorded within these structures, but unless you've got a geologic
quadrangle (we were the first state to have a complete set of 7.5 minute
GQs) you'd be hard pressed to know you were in one.

Wikipedia entry "Cumberland Gap"

"Middlesboro (Tennessee) is the only place in the world where coal is
mined inside a meteor crater. In September 2003 it was designated by
the Kentucky Society of Professional Geologists as a Distinguished
Geologic Site."

I recall reading that there is another small crater in Tennessee that
had traces of occupation of prehistoric occupants. An interesting
choice? Look at the "hare in the Moon" (Navaho).
