One of Iceland's most unusual volcanoes can be found on a peninsula far to the north of Reykjavik. There, the hard to pronounce Snæfellsjökull volcano has been unusually active when you consider its distance from the nation's main volcanic chains. In the last 10,000 years, Snæfellsjökull has nearly erupted a dozen times, covering more than 230 square kilometers in a layer of lava during that timespan.
