Tocantins River

Definition and stakes

Portrait of Annie S. Peck Annie S. Peck,  Industrial and commercial South America (1922)

“ The Tocantins River is a great artery of Brazil flowing from south to north a distance of 1600 miles, with a west affluent, the Araguaya, almost its equal in size and 1000 miles long above the union. Both rivers receive many tributaries. The flat broad valleys are overlooked by steep bluffs. The cataracts and rapids which occur on nearly all of the rivers as they come down from the plateau greatly interfere with navigation, but in their lower courses many are navigable for hundreds of miles, the Tocantins for 130. ”

“ If in countless centuries to come the ocean should continue to eat its way into the Valley of the Amazons, once more transforming the lower part of the basin into a gulf, as it was during the cretaceous period, the time might arrive when geographers, finding the Madeira emptying almost immediately into the sea, would ask themselves whether it had ever been indeed a branch of the Amazons, just as they now question whether the Tocantins is a tributary of the main stream or an independent river. ”

“ It is a question among geographers whether the Tocantins is a branch of the Amazons, or should be considered as forming an independent river system. It will be seen that, if my view is correct, it must formerly have borne the same relation to the Amazons that the Madeira River now does, joining it just where Marajo divided the main stream, as the Madeira now joins it at the head of the island of Tupinambaranas. ”
