Good evening everyone! Tonight's Daily Nature Fix is about a crack in the earth's crust that is filled with some of the clearest, bluest water in the world. It is the Silfra Fissure that runs between the North American and Eurasian tectonic plates, and it's found in the Þingvellir National Park in Iceland.
^^^Look at that water!
Silfra Fissure is an awesome sight to see. As some of my longer followers know, I have a thing for blue water. It's one of my favorite things to see. This place is particularly good for that! The water truly is some of the clearest on Earth due to it's purity. It starts out as meltwater from the Langjökull glacier... not a bad start to life. Then its filtered through miles of porous volcanic rock for some 300 years before it makes it's way to the rifts in this valley.
^^^Some of the rocks in this photo are almost 40 feet underwater... yet perfectly visible.
"Clear" is almost an understatement. The visibility in the Silfra Fissure is around 300 feet! That depth is nearly unheard of. The water is awfully cold, around 39°F, which is another factor in keeping the water so clear and clean. Though be it cold, tourists can dive the rift using drysuits... but we've never gone for that. I'm plenty happy with viewing it from above. :)

This place is definitely a must-see if you visit Iceland. For me, it was the highlight of the entire Þingvellir National Park. It's part of the famed "Golden Circle", so if you go to the country, I'm sure you'll visit it. I hope you get nice weather as well, as the bright sun helps the water glow and even more blue.
