Silfra Fissure
Between Iceland’s Thingvellir National Park and the tectonic plates of Eurasia and North America, lies the Silfra Fissure. The fissure was formed in 1979; it is characterized by a crevice that goes 63 meters deep. The fissure itself expands by about 2cm per annum.
It is regarded as the clearest water on Earth courtesy of the presence of fresh water in it. It can be seen from 100m away for this very reason, and because of the squeaky clean water, the area has become a famous diving site.
