About 250 miles east of La Paz (11,000 foot elevation) in the Andes of Bolivia, down the Beni river to where it meets the Mamore river (elevation about 500 feet), was the Cabarabe Culture said to have begun circa 500 a. d. but probably earlier, a vast area of settlements on that floodplain with elevated connectng roads, canals, temples, pyramids, elevated farming and forestry “islands,” that system of settlements radiating four hundred miles in all directions (discovered by Light Detection and Ranging, LIDAR) from ancient Cotocoa and Landiva, reminiscent of the Olmecs and Mayans of Central America, though undoubtedly many of the Cabarabe had moved down from Tiwanaku (near La Paz) when the port there on lake Titicaca grew far away as Titicaca greatly receded after the Ice Age.
