Cave formations are called speleothem, from the Greek word spelaion, cave and thema meaning deposit. Almost all of them are made of calcite, the crystal of calcium carbonate. Different minerals and different movements in the water account for an incredible variety of cave formations.
Photography by Alice Mary Herden. Take a Hike at Dames Cave and Peace Cave. Those who dare to take those steep steps underneath the earth and into the unknown world which holds so many mysteries are not only seen as adventurous explorers but have an opportunity to witness how nature works. These caves are referred to as karst caves.
