The first image is of a small pool of water in the cave. They are not sure what gives it its blue color except that it is full of minerals from the cave drippings and it has no life in it so it is completely clean and clear. Whatever the reason it is beautiful!
Bridal Cave it estimated to be about 2.5 million years old! It is located near the Lake of the Ozarks in Missouri.
It is amazing to see and they give a awesome tour. I highly recommend it if you are ever in the area.
