The weather turned today so instead of a walk I joined an organized "excursión" to the glacier at the base of the tallest mountain and dormant volcano Cerro Tronador (thunder maker). Decidedly good decision. Stayed dry and warm and got to see my first glacier. Parque Nahuel Huapi is Argentina's first and oldest national park with some great history involving rich patrons, dead Jesuits and poisonous liquor made of mushrooms. Well more or less and a wooden statue of a virgin wrapped in leather and rediscovered after 3 hundred years.
