The giant submarine smectite cones that rise from the 70 meters deep seafloor at Eyjafjörður. Strýtan is a one of a kind, and one that has recently been discovered and the only one we know of in the world. It was in 1997, Erlendur Bogason and his friend Árni Halldósson captain on the whale watching boat Níels Jónsson found this 55 meters high cone we called Strýtan. The top of the cone is 15 meter under the surface and we estimate it is around 100 litres of 75°C hot water per second coming out of the cone. Strýtan started developing at the end of last ice age 10.000 years ago and they are made from magnesium-silicate from the sea. Cones like these are usually found at 2000-6000 meters deep.
