Iceland is a geological feast for the eyes. Over the past 20 million years, volcanic eruptions have created a rugged landscape with diverse features, including moss-covered lava fields, enormous craters, bizarre geological formations, ice caves and lava tubes. These are all monuments to the island's unique location along the mid-Atlantic ridge, where the North American and European tectonic plates meet.
The Berserk Lava Field
The central western peninsula, Snaefellsnes, is steeped in mythical Icelandic sagas. The rugged Berserk Lava Field covers vast swathes of the region, stretching between the mountains and the sea. Its sources are four prominent, but different-sized scoria craters that lie in an east to west row and probably erupted at short intervals approximately 3,600-4,000 years ago, almost damming Lava Bay in the east, where the old main road crosses.
The lava flows created two lakes on the southern side that were obstacles to settlers. People once walked or rode horses along the southern edge of the lava or travelled past it by boat. Today three roads cross the lava field. We hike along one of the old walking paths through the lava and back.
