Dugway geodes, found within the Juab Formation in Utah, are renowned for their diverse and striking forms. These geodes are notable for their open shells, which often have thick walls. The interior surfaces of these shells are typically coated in fine crystals that form on botryoidal, or grape-like, structures.
The specimen features a deep chamber and microscopic blue druzy quartz. There is an opening on the other end allowing light to enter the chamber from two sources. This quartz exhibits a unique fuzzy texture and is especially remarkable for its ability to glow under long-wave ultraviolet (UV) light, as shown in the accompanying photograph.
Frequently referred to as a "Thunder Egg," this type of geode is obtained directly from miners working in the region.
