What are Geodes and Thundereggs?

Geodes are spherical to subspherical rock structures with an internal cavity lined with mineral materials. They have a durable outer wall that is more resistant to weathering than the surrounding bedrock. This allows the geode to survive intact when the surrounding bedrock weathers away. The mineral lining the cavity is often a scintillating druse of tiny quartz crystals underlain by multiple bands of translucent gray and white agate. Many are lined with more spectacular treasures.

Thundereggs are agate-filled nodules found in various parts of the Western United States. They range in size from 1/4 inch to as large as 5 feet in diameter. Generally, they are about the size of oranges. All are similar on the exterior, but no two are alike in pattern, design or color on the inside.
