The icicle shaped rocks that hang down from the ceiling are called stalactites. The icicle shaped rocks that push up from the cave floor are called stalagmites. Remember stalagmites push up with all their mite from the floor, while stalactites hold on to the ceiling really tight. Generally the dark colored stalactites and stalagmites are considered to be dead and the light colored ones are living. This simply means that they are no longer receiving a growth source.
Scientists believe that it takes nearly a thousand years for a stalactite to grow.
Formations made from a dripstone deposit in the caverns are said to grow 1 inch every 100 years. You can also enjoy finding calcite crystals as well as intricate erosion features such as inverted potholes, draperies, domes, and pits. You can also expect to see a few bats. They are usually only about four inches or smaller from head to tail. Females are a light brown color.
