Lake Thingvellavatn on Iceland. In more than one sense this place is wondrous and mystic. Geologically, the Thingvellir area is part of a fissure zone running through Iceland, being situated on the tectonic plate boundaries of the Mid-Atlantic Ridge. The faults and fissures of the area make evident the rifting of the earth’s crust.

Global diving travel has become increasingly easy over the last decade or so, providing easy access to a growing number of tropical and exotic destinations. So, for many divers residing in cooler climates or new to the sport, it is tempting to look only towards these warm distant destinations and perhaps ignore the wealth of marine life on their own doorstep.
