Hvannadalshnúkur is the tallest mountain in Iceland. It forms part of the crater around Öræfajökull, which conceals a particularly violent volcano. It had a massive eruption in 1362 that made the surrounding area unsettleable for decades. When people finally returned to it, forty years later, it was named Öræfi, which meant 'the area without a harbour'. Now, it is synonymous with ‘wasteland’.
