Sad news which I just saw in the US caving forum:
http://forums.caves.org/viewtopic.php?f=6&t=10483

Wes Skiles was one of Florida's foremost & pushiest cave divers; one of the early Americans to adopt side-mounted cylinders to explore tight caves.  He also happened to be a serious environmentalist & a really good guy who looked after many of the CDG crew over the years during our visits.  Another one bites the dust..... 

Check out the (very high) standard of his underwater cave photography in the latest edition of National Geographic http://ngm.nationalgeographic.com/2010/08/bahamas-caves/skiles-photography including a front cover shot.

Huge, huge loss....
