Lake Nahuel Huapi (Araucanian for ‘Lake of Tiger Island’), which is comparable in size (529 km²) to Lake Constance, is a vast glacial trough into which several glacial streams converged. This explains its intricate network of fjord-like branches. It is known as the ‘Lake Lucerne’ of Argentina, whilst the surrounding mountain landscape, including the skiing paradise at Cerro Catedral (2,388 m), is referred to as the ‘Argentine Switzerland’. - Book: Picture 196 - Argentina - 1973
