PNAS has an interesting paper on using AI and Machine Learning to try and identify new Nazca Pampa geoglyphs in the Peruvian Nazca Desert. It’s a fun little lunchtime skim with a few nice images of some of the newly found geoglyphs.

PNAS: AI-accelerated Nazca survey nearly doubles the number of known figurative geoglyphs and sheds light on their purpose
