TAO completed its first major field project at the Puna Pau topknot quarry. The majority of the red scoria caps that once adorned megalithic statuary were carved in this small volcanic crater. Many of the topknots or pukao that were carved here were at one point hoisted atop statues that reach several meters in height. A few other pukao never reached their destinations, and some even remain in the quarry site today. The only pukao that remain atop statues today are reconstructed examples. As statues toppled on the island, these massive topknots, sometimes reaching more than two meters in width and two meters tall, came crashing down as well.
Students who participated in the Puna Pau Project began by mapping the terrain and pukao locations in the crater and surrounding areas. The only survey instrument was a theodolite left on the island decades before by archaeologist William Mulloy.

The students created a detailed two-dimensional map using the theodolite and modern GIS software. The project also carefully photographed and documented each individual pukao.
With tape measures and digital cameras, students measured and described the details and condition of the topknots. Their ultimate goal was to reproduce the site in digital format for conservation and research purposes. Upon gathering data and completing the preliminary mapping exercise, students took the project a step further to create three dimensional digital models of the terrain and each individual pukao. The complete report for the project was co-authored by all participating students and published in the Rapa Nui Journal.
