Mayan Stairway reveals a longer chapter of missing history. New glyphs revealed by a hurricane at Dos Pilas, Guatemala, tell of "the attack on Dos Pilas by Calakmul in this powerful kingdom’s strategy to control the river trade routes between the Maya Lowlands and the Highlands of Guatemala in the Southwestern Petén and the resulting Dos Pilas’ acceptance of a subservient role in this affair." Same report in Spanish. There is also a weak New York Times report.
