Full Show: A volcano can be described as part of the earth's plumbing system. Magma, or molten rock from under the earth, pushes upward through a sort of natural pipe and sometimes explodes lava out of the ground. Volcanoes created many of Idaho's mountains and plains.

Learn more about Volcanoes from this month's guest experts, seismologist Jim Zollweg and geos

Season 1 (2-28-2000)
Full Show: Volcanoes have shaped both the Earth and human history for eons. Much of Idaho's own topography has been molded by a tectonic plate moving over a "hot spot" of plume-generated volcanic activity. Learn more about this "explosive" topic from husband and wife volcanologists Martha Godchaux and Bill Bonnichsen.
