Along The River That Flows Uphill - From the Orinocco to the Amazon

The Casiquiare is unique. 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. This book offers information about the river and the fierce Yanomani tribe.
