On to 2016: There is not nearly as much ice, but the colors are more visible and the formations are still interesting. Rock and ice make the same formations. I've seen stalagmites, stalactites, columns, cups, ribbons, hanging straws, broken/fallen straws fused to the floor, curtains, cauliflower, etc. made of calcium minerals in caves in KY and WV. The same shapes form in ice if the conditions are right.
