This is called the Double Column. It is 47 feet tall and is composed of both stalactites and stalagmites. The area it is in is called Giant's Hall. The ceiling is over 60 feet in height.
In this picture you can see some of the formations that are called totem poles. I thought they looked like carvings made in wood. If you looked closely, you could see all types of shapes in the rocks.
I love these formations that look like fringe or draperies. It takes about 120 years to form one cubic inch. It's hard to comprehend how many years it has taken for these caverns to form.
There are different colors in the rock. Some are white and almost translucent and some have more of a yellow or gold cast. It depends on what impurites from the soil have seeped down.
This is called Dream Lake. The bottom of the photo is a reflection in the water of the stalactites hanging from the ceiling. The water is not deep, only 18 to 20 inches at it's deepest point.
