Submerged cemetery, Florida

[Erato]

"The archeological remains of a 19th century hospital and cemetery have been found on a submerged island near Garden Key, the second-largest island in the Dry Tortugas National Park near Key West, Florida."

How fascinating. Makes you wonder just how much archaeology is lurking beneath the waves still waiting to be discovered.

Medical science has come a long way since the mid to late 19th century.  New knowledge is always waiting there to be found.

  I would have liked a bit more information on how the island came to be so far under water. I presume some sea level rise, but there is also mention of dynamic conditions causing islands to move?

Good afternoon,

I assume this is Bird Key (formerly Booby Key) which was lost in 1935. Said to contain graves of prisoners from the nearby hospital and also civil war graves.
