Puna Pau is a quarry in a small crater or cinder cone on the outskirts of Hanga Roa, in the south west of Easter Island. Puna Pau was the sole source of the red scoria that the Rapanui used to carve the pukao (topknots) that they put on the heads of some of their iconic moai statues.
The stone from Puna Pau was also used for a few non-standard moai, including Tukuturi, and also for some petroglyphs.
