The great rivers that run through Patagonia have their source in the Andes. The gradient is gentle, and the watercourses take their time before pouring into the Atlantic Ocean. But in the rainy season, when the storms rage in the peaks of the Cordillera, the rivers swell. Then floods threaten people, animals and crops. The inhabitants of both banks use the many fords as river crossings. The photograph shows a scene that used to be characteristic of life in the pampas, but is becoming increasingly rare today as a result of Argentina's economic development: A herd of four hundred Hereford cattle is being driven through the Río Alumine (Neuquén province) and taken to the next estancia. These transports are increasingly carried out with the help of trucks, at least where bridges allow the rapid crossing of Patagonia's rivers and streams. - 1973
