A high-resolution LiDAR survey in the Llanos de Moxos has revealed an expansive network of crescent-shaped moats and earthen platforms that were central to the Casarabe culture's seasonal rituals. Research indicates these structures were utilized for the 'Festival of the Rising Silt,' a complex hydro-ceremonial event where participants used the nutrient-rich river mud to build ritual mounds while performing music on bone flutes.
According to lead researcher Dr. Elena Morales, the spatial distribution of the moats aligns perfectly with the rising of the Pleiades during the onset of the rainy season. This discovery provides a new understanding of how ancient Amazonian societies integrated sophisticated hydraulic engineering with cultural heritage celebrations, using the physical manipulation of the landscape as a form of communal worship.
