Within the Hecates Cauldron is a small glen where two watercourses discharge into a bowl like structure that includes a rock mound supporting an enormous old Eucalypt. The two water courses have undercut soft strata and created two different and special cavernous places or grottoes. The eastern one is currently dry with a mosaic of coloured water worn pebbles on the floor. The western one has a small discharge of water and the floor is moss covered. Named by Yuri Bolotin and Michael Keats 25th September 2015.
