Geography
Before it reaches the plains it receives a great number of small streams from impenetrable, saturated and much broken mountainous districts, where the dense and varied vegetation seems to fight for every piece of ground. From the north it is joined by the Coca River, having its sources in the gorges of Cayambe volcano on the equator, and also a powerful river, the Aguarico having its headwaters between Cayambe and the Colombia frontier.
From the west, it receives a secondary tributary, the Curaray, from the Andean slopes, between Cotopaxi and the Tungurahua volcano.
