 However, these beautiful natural formations are delicate and easily damaged and destroyed.Visitors in Georgies Hall, Honeycomb 1 cave and Tailender Cave have already caused serious, and in some cases, irreparable damage to speleothems and calcite formations in the caves, by tracking mud and dirt across the delicate surfaces by not sticking to marked paths, or due to irresponsible cave exploring.Mud and dirt, deposits of hair, lint from clothing and skin follicles, and excess nutrients trekked in from the outside world build up in the caves due to them being cut-off from the outside world.
