We know how high the mountains are and how deep the oceans. Satellites have scanned every inch of the earth, but no one knows what lies just below the surface without going there. It is the last uncharted place on this earth. Who knows how many more caves and passages have yet to be discovered. By joining a grotto you can learn about the proper equipment and techniques used in caving.
Most caves are on private property.
You must have permission from the land owner to go into the cave. Always tell someone what cave you are going in and when you plan to be out. Never go in a cave alone. Always have at least four people in the group. Always carry at least three different light sources that will give you twenty four hours of light.
