ON THE SPINE OF THE ATLANTIC

Iceland is perched directly atop the Mid-atlantic Ridge, a tectonic boundary that crosses the island and continues about 10,000 miles farther to the south. native German has traveled all over the island in search of new dive sites and developed tours for many of the most fascinating ones.

After Banfi has finished exploring and photographing Silfra’s Big Crack, Hall, Cathedral, and Lagoon, he and his team decide to move on to new adventures. Iceland has hundreds of other crevasses and cave systems to explore that can’t be reached by car, so Banfi and his crew climb back into their helicopter and fly off to the next underwater canyon 10 minutes away. Silfra fissure is famous and attracts thousands of divers a year, but many other entrances to subterranean cave systems are secret and isolated, and very few will ever get to explore them.
