Power of Dettifoss
Dettifoss is a waterfall in Vatnajökull National Park in Northeast Iceland, and is reputed to be the most powerful waterfall in Europe. The water comes from the nearby Vatnajökull glacier, whose sediment-rich runoff colors the water a greyish white. The superlative of "most powerful" comes from its water flow times its fall distance. The water of the wide River Jökulsá falls for more than 144 feet, causing a massive, crashing spray.
