Vatnajökull National Park
The west of Vatnajökull is also largely dominated by volcanic activity. Two of the world's largest fissures and lava eruptions in historical terms took place there: near Eldgjá (934) and Lakagígar (1783–1784). Vonarskarð, northwest of the glacier, is a colourful, well-tempered area and is a watershed between north and south Iceland.
