Planchón-Peteroa is a huge volcano system. It sits right on the border between Argentina and Chile. This amazing place is actually made up of several volcanoes that have grown over many years. It also has some big, bowl-shaped areas called calderas. These calderas formed when parts of the volcanoes collapsed. The main volcanoes here are Volcán Planchón, Volcán Peteroa, and Volcán Azufre.
About 11,500 years ago, a large part of the volcano complex collapsed. This caused a massive landslide of rock and dirt. This landslide, called a debris avalanche, flowed down the Teno River. It traveled all the way to the Central Valley in Chile.
Peteroa volcano has a crater lake at its top. A crater lake is a lake that forms inside a volcanic crater. At the base of Planchón volcano, you can find Lagunas de Teno. The Vergara International Pass is also located in this area.
