Liam trying on a dead Guanaco´s jaw for size in the altaplano between El Calafate, Argentina and Torres del Paine National Park, Chile. We had a five day "father and son" trip to southern Patagonia to explore the cold, windswept and icy region. In this mini-hike, we found several dozen guanaco skeletons, some long-dead, some freshly killed. Since many where found near a fence, we assumed that the Puma ran them to the fence where the grasseaters were trapped.
