The Waitomo district is filled with underground limestone caves containing formations such as the stalactites in this photograph. Stalactites are created when water containing calcite (calcium carbonate) drips from the ceiling. Over time the calcite builds up to form stalactites. In this cave the water has dripped in many places, creating a field of beautiful formations.
