I doubt Medieval cathedral architects had access to underwater caves for inspiration but submarine caverns certainly could have inspired them.
The reef in front of our beach is like Swiss cheese: it is riddled with holes and little (and some not so little) tunnels and passages called swim-throughs. Many/most are open to the surface. The sunlight streaming in is like sunlight pouring through the stained glass of a cathedral. The water changes the color of the light with different depths and distance. Divers' bubbles react with the light. It is a magical spiritual place.
These photos are from two of the most beautiful dives I've ever done. first at Shacks - right out our front door - and then at Natural.
For much of the year Shacks, which faces due north into the winter waves, is just too rough to safely dive. But when it's good, Shacks is a beautiful dive. Yesterday was an exceptional day: 80-to-100 foot visibility, no waves and no surge, no current, clean, clear, warm, as close to perfect as it gets. Quite a first-ever diver for our new friends, father-and-son, Jeff and Jack.
Our second dive at Natural was every bit as good. Natural has a penchant for butt-kickin' south currents, especially in the summer. We expected to get caught in one of those currents and we were prepared: we planned to do a drift dive three-quarters of a mile to Wishing Well. Once again, Natural threw us a hooking, sinking, sliding curve. Not only was it not ripping from the south, there was a slight north current. Again, as perfect as it gets: clean, clear, warm and mostly free ride home on that north current.
As you've probably figured out, I love to scuba dive. I'm quickly approaching 300 dives. This day and these two dives are stand outs.
(And just to add and exclamation point to the day, we took the horses swimming just before sunset. What a day!)
