Controversial Study Suggests Vast Magma Pool Under Washington State

WASHINGTON -- A vast pool of molten rock in the continental crust that underlies southwestern Washington state could supply magma to three active volcanoes in the Cascade Mountains -- Mount St. Helens, Mount Rainier and Mount Adams -- according to a new study that's causing a stir among scientists.
