North America may not share political borders with Europe, but that won’t stop you from visiting the convergence of the two massive continents in Iceland.
The Eurasian and North American continental plates meet in a stunning landmark, known as the Silfra fissure, within Thingvellir National Park. Forming part of the divergent tectonic boundary between the two plates, the dramatic rift is found at the bottom of Thingvallavatn Lake, a body of water known among st scuba divers for its exceptional visibility and and breathtaking sights.
For many, Silfra is the dive of a lifetime. Not only can you touch two separate continents during a dive, but the frigid glacial water is remarkably blue and astoundingly pure: Visibility typically extends over 300 feet in most parts of the fissure, making it home to some of the clearest water in the world.
The Silfra fissure opened up in the late 18th century and continues to change to this day. Each year, the two continental plates drift apart by approximately three-fourths of an inch, creating a gradual buildup of geological tension that is released periodically through seismic events.
