Geirfuglasker ("Great Auk rock") was a small islet near Reykjanes, Iceland. It was volcanic rock with steep sides except for two landing places. The rough surf around the island usually made it inaccessible to humans, and one of the last refuge for the Great Auk (which was also called "Garefowl" — "geirfugl" in Icelandic). In a volcanic eruption in 1830 this rock submerged. The surviving Great Auks moved to a nearby island called Eldey and were wiped out by humans several years later.
