Gaucho conjures up an image as iconic as the word cowboy. But according to historians and anthropologists, their semi-nomadic culture disappeared at the end of the nineteenth century, and no one has seen the gauchos since. Until now. Twenty-five years ago, the government of Chile began building a road into Chilean Patagonia, one of the least-populated regions in the world. In 1995, when Nick Reding traveled down that still-unfinished road into an unmapped river valley, he found himself in a closed chapter of history: a last, undetected, and unexplored outpost of gauchos so isolated that many of them, some of whom are boys as young as thirteen, still live completely alone with their herds, hours on horseback from the nearest neighbors. In 1998, Nick returned to the valley to witness what happens when time catches up to a people whom history has forgotten.
