Researchers from Binghamton University, at the request of an indigenous community group on Easter Island, have created a high-resolution 3D model of the Rono Raraku quarry, where 95 percent of the island's moai statues were carved. Using drone flights and over 11,000 overlapping photographs stitched together via photogrammetry, the model documents the quarry in unprecedented detail, including 133 quarried voids, 400-plus unfinished moai, and evidence of 30 distinct clan-based carving areas. The model is freely available online and was motivated by a 2022 wildfire that threatened the site.
The 3D map matters because it provides a permanent, accessible record of a fragile archaeological site vulnerable to fires and environmental degradation. It also offers new insights into the social organization of the Rapa Nui people, revealing that moai production was decentralized among autonomous clans with distinct carving methods and artistic expressions. This challenges previous assumptions and deepens understanding of how a complex society operated on a remote island with limited resources.
