Now at our first stop in Iceland, Vopnafjörður. Don’t ask me to pronounce it, I’m not entirely sure it can be done. When we got out of the car and started walking, this really didn’t look like waterfall country (as a matter of fact, it seemed perfectly reasonable that early moon astronauts trained here, in preparation for lunar topography). Then we came around the bend.....Dettifoss claims to be the “most powerful waterfall in Europe”
