Tindfjallajökull, one of the oldest late-Quaternary volcanoes of the eastern volcanic zone of Iceland, is seen here from the ESE. The Thórsmörk ignimbrite accompanied formation of a 5-km-wide caldera during the Pleistocene. The NW rim of the caldera is overtopped by the Tindfjallajökull icecap, which forms the smooth flat surface at the summit. About a dozen small eruptions took place during the late Pleistocene or early Holocene, mostly from vents north and west of the caldera.
