Wyndham Jurassic intrusion and Paleogene basalt
This spectacular rock face is Jingera Rock, a 180 million year old intrusion exposed by erosion. This is part of extensive igneous intrusions that heralded the breakup of eastern Gondwana. About 1.5 km east of the village is an unrelated remnant of a 40 million year old basalt lava flow. The flow is part of the eruptions forming 4300 square kilometre Monaro Volcanic Province beyond the escarpment to the west. Lava flows cascaded down the coastal hinterland valleys off the highlands.
