Volcanoes constantly shape the world we live in and influence everything from geography to agriculture, but very few of us have ever seen one.  This 12 X 8 display features many of the products of volcanic activity - ash, cinders, pumice/scoria, obsidian and volcanic clay - along with an illustration of the anatomy of an eruption.  A colorful visual aid featuring real specimens and straight-forward descriptions, this exhibit is a great introduction to volcanology for any age.
