This video describes and explains the geology of the Thingvellir Graben, a part of the West Volcanic Zone in Iceland and an area of great natural beauty. The focus is on the spectacular structures seen in Thingvellir, but the video also describes the older rocks, including an extinct central volcano and an associated collapse caldera, as seen from the Golden Circle on the way from the capital Reykjvik to the Thingvellir Graben.
