The Hvannadalshnúkur rises 2,110 meters above sea level. It is the highest mountain in Iceland. It is located in south-eastern Iceland in the north-western corner of the summit caldera of the volcanic massif Öræfajökull. On the top of Öræfajökull is a caldera which is approximately 5 km wide and about 550 m deep. This caldera is filled with glacial ice from where numerous alpino type glaciers flow far down. The summit massif is built up from silica-rich volcanic rocks.
The photo has been taken precisely at midnight. In mid-June the over 2,000 m high towering peaks get the midnight sun.
