Putumayo River

The Ica or Putumayo River is one of the tributaries of the Amazon River, west of and parallel to the Yapura. It forms part of Colombia's border with Ecuador, as well as most of the frontier with Peru. Known as the Putumayo in the former three nations, it is called the Ica when it crosses into Brazil.

In the late 19th century, the Ica was navigated by the French explorer Jules Crevaux (1847-1882). He ascended it in a steamer drawing of water, and running day and night. He reached Cuemby, above its mouth, without finding a single rapid. Cuemby is only from the Pacific Ocean, in a straight line, passing through the town of Pasto in southern Colombia. Creveaux discovered the river sediments to be free of rock to the base of the Andes; the river banks were of argillaceous earth and the bottom of fine sand.

Today the river is a major transport route. Almost the entire length of the river is navigated by boats.

Cattle farming, along with the rubber trade, is also a major industry on the banks of the Ica. Rubber and balata from the Ica area are shipped to Manaus, Brazil.

On March 1, 2008, Raul Reyes and 14 of his fellow Revolutionary Armed Forces of Colombia guerrilla companions were killed while on the Ecuadorian side of the border by Colombian military forces.
