Damn! It's that Iceland again! First came Gulfoss, now Dettifoss. I REALLY have to go there. I am getting the idea that Iceland is the ultimate place to go for "foss". And for the true sense of grandeur in this pic, make sure you see it in large.
A truly remarkable pic. There is even a tiny little person at the top for scale. And its remarkable in another way in that you get a real sense of the Atlantic ridge rift in this pic.
