Alkefjellet (‘mount guillemot’) is the nesting location for over 60,000 breeding pairs of Brünnich’s guillemots. The cliffs are made of basalt columns up to100 m high, interspersed with a dark layer – a dolerite intrusion. The molten rock, as it intruded caused the limestone in the contact zone to re-crystalize and form marble.
