"The two writers hired a boat and a guide to take them 1,000 miles up the Orinoco and along the Casiquiare to the Rio Negro, which flows into the Amazon." - University of Chicago Press (in 2026 a 404).

"The Casiquiare is unique. There is no other river like it on the planet. Somehow it manages to unite the two river systems of the Orinoco and the Amazon that should, by rights, be entirely separate, and the Casiquiare performs the astonishing feat of flowing up and over the watershed that divides them. Richard Starks and Miriam Murcutt travelled along the Casiquiare at the behest of the Royal Geographical Society-and in the footsteps of exploring greats like Alexander von Humboldt and Aimé Bonpland-to gather information about the river and the fierce Yanomani tribe that still maintains its austere and primitive lifestyle in the region." - authors' website
"The Casiquiare river is a distributary of the upper Orinoco flowing southward into the Rio Negro, in Venezuela, South America. As such, it forms a unique natural canal between the Orinoco and Amazon river systems. It is the world's largest river of the kind that links two major river systems, a so-called bifurcation. The area forms a water divide, more dramatically at regional flood stage.
"The Yanomami are a group of approximately 35,000 indigenous people who live in some 200-250 villages in the Amazon rainforest on the border between Venezuela and Brazil."

196 - "Of course, at no time does it run uphill. Instead, the bed of the upper Orinoco has been slowly rising - elevated by thick deposits brought down from its source - so now it is a few feet higher than the bed of the Casiquiare. The watershed - the high ground that separates the Orinoco from the Amazon - is therefore right there, at the bifurcation. The Orinoco sweeps up to that watershed - the point at which each drop of water must decide whether to stay in the Orinoco and head for the Caribbean, or opt for the Casiquiare and go for the South Atlantic - and simply tips some of its water over the edge."
