Interesting. I've been diving for over 40 years from Costa Rica to Nome. I've logged over 4,000 dives in this time and some of my very favorite have been in Alaska. I live in SE so much of my diving has been here. There are wonderful dive sites here. Sure, you need to sniff around more than The East Cape in the Baja but there are fantastic dives here in Alaska. My favorite sites are out at Coronation Island. It's right where the warm Japanese currents hit the Islands of SE . World class. If you are an adventure diver (wreck etc) don't miss this spectacular area full of beauty and archeological wonders.
