In Iceland, the interior of many volcanoes is accessible - due to erosion in the East Fjords eg. (see: Breiðdalsvolcano), or due to caldera eruptions (see: Krafla Caldera). What's special about this cone, Þríhnúkagígur, is that you may enter a still rather closed feeder system here where the walls have not yet been destroyed by erosion.Reykholt (talk) 08:29, 9 July 2016 (UTC)
