MOLTEN ROCK, or magma, rises in convection cells, like water boiling in a pot. The left side of this illustration shows the traditional view of a hotspot as a plume of magma rising from the earth's core. The right side shows another theory that the Yellowstone hotspot originates at a much shallower depth.

Dog Hooked to Travois for Transporting Goods.
