larger, deeper pool of magma below the already huge reservoir near the surface
. From the article:On Thursday, a team from the University of Utah published a study, in the journal Science that for the first time offers a complete diagram of the plumbing of the Yellowstone volcanic system.
The new report fills in a missing link of the system. It describes a large reservoir of hot rock, mostly solid but with some melted rock in the mix, that lies beneath a shallow, already-documented magma chamber.
