This unusual landform is possibly best appreciated from above, as in this view from the glider. It goes by the name of Minto Crags and, I understand, is popular with rock climbers. Geologically, it is a formation known as a Ring Dyke (one of the few in Australia). These are formed when underground earth movements create a circular fault line which then is filled by upwelling molten lava. The ring formation becomes apparent when the overlying softer rocks erode away. You can read more about Minto Crags here: www.tinyurl.com/pq8yjyq
