More than a billion years ago, a huge bubble of 2,0000F magma got trapped 10km beneath our feet and began to cool. How did the magma die? Was it a natural death or murder? Who did it and how? One thing for sure – it took a while; since magma’s really tough! Dan Gruber will guide you through this amazing journey, and you will learn what happened as the last bit of magma finally turned into solid rock.
