Other explorers got to the roof of the cave by hooking a ring over a stalactite and climbing up an attached rope. National Geographic also made their own exploration in 1924. In the Big Room you can see the broken ladder left in a pit by early explorers. Stalactites are one of the many cave formations. They form on the ceiling of caves.
Stalagmites are the largest formations.
They grow on the ground and can reach 60 feet tall and 10 feet wide. Many other formations like draperies, helicites, cave pearls, ponds and gypsum flowers exist. Also many rooms exist in the caverns. Some of these are the Big Room and the Green Lake Room. These rooms contain very interesting formations and lakes.
