Through the Heart of Patagonia

The narrative recounts an expedition across Patagonian plains, river valleys and Andean foothills, blending travelogue, field natural history, and ethnography. It describes windswept pampas, glaciers, lakes and winding rivers, the methods and customs of indigenous peoples, camp life and hunting of guanaco, with observations on huemul, puma and other mammals. The account follows routes that reveal little-known gorges, rivers and lakes and the practical difficulties of navigation and transport, and it records geological and zoological discoveries; appended technical descriptions and numerous illustrations and maps document specimens and the varied terrain encountered.
