After the waterfalls we come to the glaciers. Vatnajökull is the biggest of them all with a surface of 8400km2 and a thickness at places of 1000m. Underneath lies a volcano waiting to erupt which it might do in an uncertain future. The last eruption had been in 1996.
Grimp, your travel report is just fantastic. Would be at your place !!
Many years ago, my son had to do a lecture in school about a country, and he chose Iceland. Therefore, I learnt a lot of its history.
