Ahu are found mostly on the coast, where they are distributed fairly evenly, except on the western slopes of Mount Terevaka and the Rano Kau and Poike headlands. These are the three areas with the least low-lying coastal land and, apart from Poike, the furthest areas from Rano Raraku. One ahu with several moai was recorded on the cliffs at Rano Kau in the 1880s but had fallen to the beach before the Routledge expedition.
