From a birds eye, foreground: Joint Interagency Task Force South which conducts detection and monitoring operation . Left: Special Forces underwater training facility. Middle: Harbor used by both the Navy and Key West, music amphitheater, Eco Discovery Center & soccer field. Right: Hotels, condos and homes. Left island is Sunset Key with hotel and homes, the island on the right is unoccupied. Ships enter the shipping channel from the left, can proceed around to the right but must turn around and leave the same way as depth is very shallow except in the narrow channel. The 2 tug boats are probably waiting for either a military ship or a barge carrying jet fuel.
