Large Dugway Geode (with stand) Marcasite with Barite and Pyrite Smithsonite is a rare zincWhen volcanic activity occurred in what is now western Utah some 8 million years ago, deposits of the igneous rock rhyolite formed. As the rock cooled, pockets of volcanic gases became trapped and formed cavities. The circulation of groundwater allowed silica and other minerals to precipitate into these cavities and form layers of agate and crystal quartz over the course of millions of years. Today the result is a beautiful and unique variety of
