Giant Crystals and Caves

This is another photo from our trip to the Mid-America Science Museum last Sunday. This 500 lb quartz crystal was mined at Coleman's Crystal Mines in Jessieville, just north of Hot Springs. Arkansas has many caverns that are open to the public for exploration. A few years ago, we took the kids to Onyx Cave near Eureka Springs. I may dig around for some photos of that trip. It was really fun!
