I went to Crystal Caves with my class it was the best field trip! We saw limestone everywhere. We also saw a wall with a rock stem and if you went around it you would have good luck. We also went into one room and in the wall was pennies and dimes. - In another room we saw a ghost ,it was made of rock it also looked like he was saying oh oh. I had a great time at crystal caves and if you ever go I know you will to.
