Cave Columns in the Caverns of Sonora

Detailed Description

The Caverns of Sonora have numerous types of speleothems, or cave formations. In this image, stalactites can be seen hanging from the ceiling; stalagmites can be seen rising from the floor; and all along the walls are small formations known as "cave popcorn." The central focus of the image are several columns, which occur when stalactites and stalagmites fuse.
