LiDAR reveals hidden Maya and Andean landscapes

Environmental LiDAR has revealed Valeriana's monumental architecture, dense settlement, water infrastructure, and possible early E-Group, expanding the picture of Maya urban diversity. A separate survey near Machu Picchu reportedly mapped about 1.5 miles of roads, terraces, platforms, and zigzag construction, suggesting a broader Inca landscape. Field validation, excavation, and secure chronology remain pending for both cases, and sensational framing exceeds the evidence.
