Star pupil finds lost Mayan city by studying ancient charts of the night sky from his bedroom: "‘I was really surprised and excited when I realised that the most brilliant stars of the constellations matched the largest Maya cities,’ he told the Journal de Montréal."

A more interesting question is how a "primitive culture" could lay out geometrically precise arrangements of buildings (mapping star positions) across uneven terrain. Maybe they had help with an aerial view.
