5-1/2" Dugway Geode (with stand) a502e24fd5d073c843aeec01fed69fe8 but in rare instancesWhen 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
