Llanos de Moxos (archaeology)

An extensive pre-Columbian archaeological landscape spanning much of Beni Department, Bolivia, with human presence dating back to approximately 8850 BCE. The remains include over 4,700 artificial forest islands, monumental mounds, raised agricultural fields, canals, causeways, ring ditches, and fish weirs. The Casarabe Culture (500-1400 CE) constructed a dense settlement network of over 189 earthen mounds interconnected by causeways across at least 4,500 km2. The region was a center for early domestication of manioc, squash, and maize, and represents one of South America's most significant archaeological regions.
