Poike forms the eastern headland of Rapa Nui, and there is an abrupt cliff "the Poike ditch" across the island marking the boundary between flows from Terevaka and Poike. Poike last erupted between 230,000 to 705,000 years ago in the Pleistocene, and as the oldest of Easter Island's three volcanoes is the most weathered with relatively stoneless soil.
