This has become something of a regular event this Fall. Not an outing for a WWW (warm-water-weenie) but a rewarding adventure nonetheless.
This past Sunday (Dec 2) we had the place absolutely to ourselves. Water was clear enough, but increasingly dark and cold as we descended. One dive only, to ninety feet, half an hour of bottom time, temperature at depth just above forty.
Definitely drysuit territory, if you want to make more than one dive a day.
