My last dive of the season was 60 minutes of cave heaven using side mount and playing around with the GoPro. Andros is famous for the abundance of blue holes/ caves/ caverns and tunnels and they are really impressive to dive. As I say farewell to this one, I touch the limestone and imagine the many thousands, if not millions of years it took to form this structure. At one point in time my position seen here would have been above live coral reef, evident in the fossilized corals I see on the walls. Years later this would have been a dry cave, with sea levels much lower during an ice age. Now, I touch and wonder what marine processes will occur over the next thousand years and feel very humble and grateful to have the experience.
