I decided to look for the staghorn Coral Forest off Towers 18 and 19. Descended over sand and swam out to the reef, then went on East looking for the coral. I found the Eastern edge of the reef, then came back West and just happened onto the Forest, which is an old NOVA University project.
I found the blocks on which they grew coral. I also found the large rock in the center and surfaced to see that it was due East of Tower 19. Don't understand why I missed it on the way out, but I did. Maybe too far North. I was low on air but took a few moments to look around. A lot of the coral has been flattened by the various storms we have had. Still lots of life, but I did not see any of the Blue Hamlets that I used to find. Maybe another day.
