Something Old Below Ground
Over millions of years ago, deep under the ground, our cave began to form.
Water gradually dissolved the rock to create the cavity we know as the cave.
Today water drips into the cave bringing with it dissolved crystals that fuse together to form intricate and varied shapes.
While in the cave you will pass a variety of colorful cave formations.
Our guides will point out important features of our cave and answer questions
about the history and science of our beautiful cave.
