'Unconquered' by Scott Wallace
In 2002, National Geographic correspondent Scott Wallace joined a grueling expedition into the Javari Valley Indigenous Land in Brazil. This was no Abercrombie & Fitch walk in the woods. Subsisting on piranha stew and boiled monkey, the 34-man expedition was plagued by malaria, dysentery, armies of insects, poisonous reptiles, and sudden, fierce downpours. Their mission was to locate one of the previously uncontacted tribes, the “flecheiros,’’ or Arrow People. Feared even by other wild Indians, the flecheiros still use blowguns and arrows dipped in curare, a deadly nerve agent, to keep trespassers at bay.
