The rivers ran east

Long out of print, this is a riveting firsthand account of Leonard Clark’s search for the legendary lost Seven Cities of Cibola — reputedly home to enormous reserves of gold — in the rain forest east of the Peruvian Andes. A former U.S. Army intelligence officer, Clark is joined on his expedition by Inez Pokorny, a gutsy, multilingual female explorer. Their treacherous journey includes encounters with head-hunting Jivaro Indians, man-eating jaguars, 40-foot-long anacondas, poisonous plants, and shamanistic healers. Against the odds, Clark and Pokorny reach their destination, but nearly starve to death trying to transport sacks of gold out of the dense tropical foliage.
