But I figured if I am going to do an occaisonal blog, I better do something. So instead of breathtaking photos of volcanoes, you get the picture of a troll.
According to the well of knowledge known as Wikipedia. Trolls are members of a race of fearsome creatures from Norse mythology that often live underground in hills or caves (or according to nursury ryhmes under bridges). See hills, caves there is a link to Geology.
