Tronador is an extinct stratovolcano in the southern Andes, located along the border between Argentina and Chile, near the Argentine city of Bariloche. The mountain was named Tronador (Spanish for Thunderer) by locals in reference to the sound of falling seracs. With an altitude of 3,470 m, Tronador stands more than 1000 m above nearby mountains in the Andean massif, making it a popular mountaineering destination. Located inside two National Parks, Nahuel Huapi in Argentina and Vicente Pérez Rosales in Chile, Tronador hosts a total of eight glaciers, which are currently retreating due to warming of the upper troposphere.
