What is "hornopiren"

Hornopirén is a stratovolcano located in the Andes, in Los Lagos Region of Chile, south of Yate Volcano and east of Apagado or Hualiaque pyroclastic cone. Hornopirén lies on the major regional Liquine-Ofqui Fault. The volcano is said to have erupted in 1835, although no details are known. The name of the volcano derives from the Spanish word for oven, horno and the native Mapudungun word for snow pirén, thus Hornopirén means snow oven.
