The Casiquiare lets the Orinoco feed the Amazon
A natural channel carries water between two of South America's largest river systems The Casiquiare leaves the Orinoco and runs about 340 kilometres south to join the Rio Negro, a tributary of the Amazon. It is the largest river bifurcation on Earth, so the two giant systems are physically connected. Indigenous traders used the route long before Europeans mapped it. It sits in Mondo's world geography collection, one of 200 facts that each trace back to the reference below.
