A wide range of decorations on the cave floor include totem poles, flowstone, rim stone dams, lily pads, shelves, cave pools, and of course stalagmites. Because of the relevance CAVEs paleoclimate and paleoecology have to modern concerns, the inventory has indicated a need to resolve this data gap through future paleontological research at CAVE.
