Overview
- A peer-reviewed PLOS One study released November 26 presents the first high-resolution 3D model of Rano Raraku built from roughly 11,000 drone images.
- The analysis identifies about 30 discrete quarry zones with varied techniques, documenting 426 moai in production, 341 extraction trenches, 133 removal voids and five bollards.
- Spatial patterning and evidence of statues leaving the crater along multiple routes support decentralized, clan-level manufacture rather than centralized control.
- Experimental and mechanical results reinforce an upright “walking” transport method, including an 18-person trial that moved a 4.35-ton replica 100 meters in 40 minutes.
- The open dataset enables virtual exploration and cultural management, and the authors argue deforestation was driven by rats plus human clearing, a reinterpretation some archaeologists say needs further corroboration.
