The Geysir thermal area, containing Iceland's largest geysers, lies in the Haukadalur basin, near the southern end of the lengthy fissure system extending from Hveravellir central volcano. Hveravellir volcano occupies the NE half of the massive Langjökull icecap. A summit caldera lies beneath the ice. Postglacial lava flows flank Langjökull on the northern, western, and eastern sides. The massive Hallmundahraun lava flow, which covers 200 sq km, was erupted shortly after 900 CE.

Iceland's largest geysers are located in the Haukadalur basin, at the southern end of a fissure system extending from Hveravellir central volcano. Two geysers remain active, Strockur and Smid. Strockur geyser has not built a geyserite cone, but its rim is surrounded by a pool of water. The geyser erupts every 10-15 minutes with a short-lived burst that throws steam and water to heights of 20 m or more.

Hveravellir volcano occupies the NE half of the massive Langjökull icecap, which is seen here in an aerial view from the north with Hvítárvatn lake on the opposite side reflecting the sun. A summit caldera lies beneath the ice. One of the most prominent of a series of small shield volcanoes and postglacial lava flows flanking Langjökull produced the massive Hallmundahraun lava flow, which covers 200 sq km, and was erupted shortly after 900 CE. The Geysir thermal area, containing Iceland's largest geysers, lies in the Haukadalur basin.
