Background

Hot springs are associated with the rhyolitic Prestahnukur central volcano. The classic Icelandic shield volcano Skjaldbreidur was formed at the southern end of the Prestahnukur volcanic system, between Thorsjökull glacier and Thingvallavatn lake. The broad, low-angle shield volcano produced 17 cu km of basaltic lava flows during the early Holocene.
