East of the Andes, the Pampas form a broad lowland around the Río de la Plata. Farther south, Patagonia has a much drier appearance. On the western edge, mountain ridges and lakes mark the approach to the Andes. The north-south change matters more than any single field pattern.
The Pampas and Patagonia
Follow the Andes south on the overview, then compare land immediately east and west of the range. Choose two views at the same scale so the contrast in terrain is visible.
