The Mystery Deepens Over Why The Lost City of Cahokia Was Abandoned - Science Alert-

The deforestation explanation for the abandonment of one of the U.S.'s most famous ancient sites must be set aside. David Nield builds upon the article we reviewed last year: We Might Have Been Wrong About The Mysterious 'Lost Civilisation' of Cahokia. That reports a study of human "poop" indicated the area's population had a resurgence in 1500 CE after a low point around 1450. Nield's article says sediment core studies show no evidence of floods that would force evacuation. Further South, Tom Clynes reports that Archaeologists Discover Mysterious Monument Hidden in Plain Sight. LiDAR (Light Detection And Ranging) imaging revealed a complex at Tikal that's distinctly the style found in Teotihuacan. And even more, there's a complementary discovery of "a 'Mayan barrio' at Teotihuacan that mirrors the Teotihuacan outpost at Tikal." The speculation from these finds is exciting and an embedded video of Tikal uncovered by lidar is stunning. And a relatively small-scale find has major repercussions for our understanding of North American prehistory as Venetian Blue Beads Uncovered in Alaska Might Have Been There Before Columbus. Stefan A tells how a mere "baker's dozen" blue glass beads found at three Alaskan sites has archaeologists in a tizzy. (WM)
