I was there two weekends ago. My first time on Catalina. Amazed at how many divers were there. Interestingly, other than the classes at the buoy, didnt run into any other divers below.
Saw a GSB. Scared the hell out of me as it poked out through the kelp. It backed up into the kelp, only to swim out again a bit behind me. I wish I had a pic of my buddy as he first saw it. He was looking down as it first emerged. As he looked up arms and legs flailed as he tried to back up. Priceless. The thing was huge!
The kelp looked to be in good condition, though I have very little to compare. It was amazing swimming through the forest. Far more beautiful than I expected.
Also saw a couple barracuda, a bunch of grimaldi and large schools of fish. I have been diving in San Diego (wrecks mostly), but never saw this much life. It all made for two fantastic dives
It was 70 at the surface, 66 at 40-70'. I can't wait to go back.
