Geodes are great fun. They're much better than Easter Eggs during an egg hunt, and this one was found during such an escapade. Momma always told me "Geodes are like a box of chocolates, you never know what you're gonna get." When we cracked this one, not only did we find fluorescent Chalcedony, we also found a "snowball"! It's a decent sized geode, at about four inches in diameter.
