In southern Patagonia and especially on Tierra del Fuego and in southern Chile, the climate and vegetation only allow sheep farming. The flocks graze scattered over thousands of hectares of stony wasteland. They are only herded together for three occasions: Disinfection bath, shearing and slaughter. But then the ovejeros, the shepherd gauchos, are often on the move for days with their powerful dogs, keeping in touch with each other with high altitude fires and smoke signals. - Torres del Paine NP, Chile - 1976
