Wet Andes

The Wet Andes (Spanish: Andes húmedos) 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).^[1] Another difference is that the Wet Andes is largely devoid of rock glaciers.^[2] 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.
