Corn Syrup Model Splits Yellowstone's Mantle Plume in Two

Alexandria, VA — One of the greatest controversies in science is what’s underneath the Yellowstone supervolcano. The controversy surrounds a unique relationship between a mantle plume (like the one that powers Hawaiian volcanoes) and the subduction zone off the Washington-Oregon coast. Cutting-edge research using a model created with corn syrup, fiberglass and a series of hydraulic pistons reveals a plume sliced in half by the subducting plate. Before this research, different scientific teams had only investigated the subducting tectonic plate or the mantle plume, but not both at the same time.

The resulting model of a bifurcated mantle plume potentially answers key questions about the Yellowstone supervolcano.
