Al,
The cliffs got massed up by Ivan - Rick's was destroyed to the point that they completely rebuilt. Catcha Falling Star lost a few buildings and the almond tree by the sea was killed by all the seawater. It is now the centerpiece of their Ivan's Bar.
Most of the changes came after Gilbert. Before Gilbert there were a lot of wooden, thatch and bamboo structures. When they were completely obliterated to the point you couldnt even tell where they were located, people rebuilt using concrete. While not being immune as Accompong clearly shows, concrete does offer much more protection than wood and thatch.
There was actually less total damage caused by Ivan because of the move to concrete in 1989 after Gilbert. After Ivan in 2004, Negril still looked like Negril. After Gilbert, you almost couldnt tell there was a place called Negril. The wooden structures were nearly all gone. You could stand on the beach and see the base of the mountains in any direction. The tallest things obstructing your view were big trees lying on their side with all their branches gone.
The Black River absorbed nature as it always does - they still offer their river safari cruises and you can feed the crocs. Mayfield Falls still have their river walk and you can swim through an underwater passage and arrive safely on the pool on the other side.
YS Falls has been improved, you no longer need to be an athlete to make it to the top, they have steps and rails to make the climb much easier. They also added a zipline that takes you down the entire length of the falls. It is always fun to hear the screams of first time zipliners... (grin)
