Monte Fitz Roy is a mountain in Patagonia, on the border between Argentina and Chile. It is located in the Southern Patagonian Ice Field, near El Chaltén village and Viedma lake.
Chaltén comes from a Tehuelche (Aonikenk) word meaning "smoking mountain", due to a cloud that usually forms around the mountain's peak. Fitz Roy, however, was only one of a number of peaks the Tehuelche called Chaltén.
