Saltos de Petrohue (Petrohue Waterfalls) is a wild cascade, cut in andesite lava flows from the Osorno Volcano, on the upper reach of the Petrohue River, near its exit from Lake Todos los Santos. The average water flow is 270 cubic metres per second and, being close to the road on the lakes Route between Puerto Varas and Bariloche, the waterfall is well visited by tourists. It is surrounded by broad-leaved, evergreen, Valdivian Temperate Rain Forest. The classic cone of Volcan Osorno, whose upper slopes are covered in glaciers, due to the substantial snowfall in the moist maritime climate of the region, is one of four Andean stratovolcanoes in the near vicinity. The 2652 m (8701 feet) high Osorno Volcano is similar in appearance to Mt.Fuji. Standing in the 6 km wide caldera of an older volcano, it is known to have erupted 11 times between 1575 and 1869, Charles Darwin, in the 2nd voyage of the Beagle, seeing an eruption in January 1835. Stratovolcanoes, composed of andesite lava, ash and pumice, are common in subduction zones, where oceanic crust is drawn down under a continent.
