Geode Talk at Cave of the Mounds
This event has expired. This may be a recurring event, so please check the calendar in the future for updated occurrences.
Discover the world of geodes! These quartz-filled rocks seem unassuming on the outside but a treasure within. It’s fun to learn about them and even more fun to break them open!
Learn about the secrets of this unique rock! This free talk about geodes is geared mainly toward children and families, but anyone can participate. After the talk, the speaker will demonstrate how to open a geode and one lucky audience member will receive a free geode.
A Geode appears to be an ordinary concretion of sedimentary or volcanic rock, but they were a hollow cavity at one time that crystals have grown inside of. Some Geodes fill in completely with minerals while others are still hollow. If you break open a Geode, you will find a treasure of agate, minerals, or crystals resembling a miniature cave.
