How was the Silfra fissure created?
The Geology of Silfra Silfra is a fissure between the North American and Eurasian tectonic plates in Thingvellir National Park. The rift was formed in 1789 by the earthquakes accompanying the divergent movement of the two tectonic plates.
How long is the Silfra fissure?

Are there animals in the Silfra fissure?

Is Silfra water drinkable?
Geography of Silfra It can take the water up to a century to reach Silfra and this long filtration process results in the water being both extremely clear and drinkable.
What lives in the Silfra fissure?
Dwarf Char
Throughout the rest of the year, the only fish who live in the Silfra fissure are the Dwarf Char, a subspecies of the Arctic Char. These range in size from a few centimetres, to approximately 10cm maximum, and live down in the darker recesses near the rocks and as such are not often spotted by divers or snorkelers.
Why is Silfra so clear?
Why is the Water so Clear in Silfra? The cooler the water the clearer it is. The water temperature at Silfra is constantly between 2 and 4C (35 to 39 F), making it too cold for most creatures to live there. However, this is not the main reason for its crystal clarity.
What makes Silfra so special?
