AKA Geode

While we were in the minerals area of the Natural History Museum, Sariah and Emma would occasionally read the labels of the different minerals and such to Katherine. After a few labels, she started making up her own names for the minerals. I wish I could remember more of them, but the one that I thought was funny was her name for the enormous geode that they had on display. After examining it, she matter-of-factly informed us that it was called "The Mystery of the Rock".
