next up, cat moh is in iceland at the thingvellir national park, taking an icy dip between two tectonicg and creeping. iceland is a country alive. sat on a fault line between two tectonic plates, and enduring brutal weather conditions, it's constantly being shaped by powerful natural forces. which is why i have come to thingvellir national park, because here, back in the 18th century, earthquakes tore a rift in the valley and left behind what some say are the clearest waters in the world. so i'm joining a tour group to snorkel in what is called the silfra fissure. our group is so international, even our guide is an italian. basically, we have two reasons to be here. first of all, silfra is the only place on earth you can actually dive between two tectonic plates. as i show you guys over there, there is the edge of the american tectonic plate. five kilometres on the other side of the valley there is the beginning of the eurasian tectonic plate. the silfra fissure sits between these two plates, which move apart at 2.5 centimetres a year. when it formed, glacial meltwater filled the gap. w
