In Colombia it is the Caquetá, rising in the Andean foothills near the headwaters of the Magdalena and gathering tributaries as it moves southeast. When it crosses into Brazil, the same water becomes the Japurá. Together these are 2,820 kilometers of moving water that eventually slip into the Amazon through a network of channels so braided that a colonial administrator named Francisco Xavier Ribeiro Sampaio spent his 1774 voyage trying to determine which of the eight presumed mouths was real. His answer: only one. The rest are furos and canos, the diverting side-channels by which Amazonian rivers give and take territory with the land they cross.
