# Stóra-Björnsfell

Stóra-Björnsfell (Icelandic pronunciation: ​[ˈstouːra-ˈpjœr̥sˌfɛtl̥]) is an elongated medium-sized tuya located in Iceland. It contains pillow lava, hyaloclastite and sheet lava. The volcano formed when a subglacial eruption occurred beneath an ice sheet during the last ice age. Stóra-Björnsfell's pillow lava appears originally to have erupted from a fissure.
