Andes
The Andes or Andean Mountains () are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. This range is about long, about wide (widest between 18° south and 20° south latitude), and of an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.
Wet Andes
The Wet Andes () is a climatic and glaciological subregion of the Andes. Together with the Dry Andes it is one of the two subregions of the Argentine and Chilean Andes. The Wet Andes runs from a latitude of 35°S to Cape Horn at 56°S. According to Luis Lliboutry the Wet Andes can be classified after the absence of penitentes. In Argentina well developed penitentes are found as south as on Lanín Volcano (40°S). The glaciers of the Wet Andes have a far more stable line of equilibrium than those of the Dry Andes due to summer precipitations, low thermal oscillations and an overall high moisture.
