Monte Fitz Roy is a mountain located near El Chaltén village, in the Southern Patagonian Ice Field in Patagonia, on the border between Argentina and Chile. First climbed in 1952 by French alpinists Lionel Terray and Guido Magnone, it remains among the most technically challenging mountains for mountaineers on Earth.
Monte Fitz Roy is the basis for the Patagonia clothing logo following Yvon Chouinard's ascent and subsequent film in 1968.
