José Luis Fonrouge
José Luis Fonrouge was Argentina's foremost 20th-century mountaineer and a visionary pioneer of lightweight alpine style in Patagonia. In January 1965, at just twenty-two years of age, he and Carlos Comesaña completed the historic first ascent of the Supercanaleta on Cerro Fitz Roy, conquering 1,600 metres of vertical ice and mixed rock in a single push.

Biographical Record & Archival Chronicle
Born on November 21, 1942, in Buenos Aires, Argentina, José Luis Fonrouge learned the art of vertical granite on the crags of Tandil and the high peaks of Bariloche. In the mid-1960s, while heavy international expeditions mounted prolonged sieges with fixed ropes across Patagonia, Fonrouge championed a radical new philosophy: moving fast, light, and self-contained in pure alpine style. In January 1965, accompanied by his trusted nineteen-year-old partner Carlos Comesaña, Fonrouge approached the terrifying, unclimbed 1,600-metre ice couloir splitting the southwest face of Cerro Fitz Roy. Carrying only two days of dried provisions and minimal gear, the young Argentines ascended 1,000 metres of 85° ice, bypassed the Bloque Empotrado, and negotiated sustained rock pitches along the upper ridge to claim the second ascent of Fitz Roy and the first true alpine-style masterwork in Patagonia. In 1968, Fonrouge returned to the Chaltén massif to make the second ascent of Aguja Poincenot via a brilliant new route. His exploratory climbs extended across the Peruvian Andes and the European Alps, and he later served as President of the Federación Argentina de Ski y Andinismo (FASA). Fonrouge passed away on August 20, 2001, celebrated as a founding father of modern South American mountaineering.

Cerro Fitz Roy
Cerro Fitz Roy, also known as Monte Fitz Roy or Cerro Chaltén at 3,405 meters (11,171 ft), is a world-renowned granite monolith situated in the Southern Patagonian Icefield near El Chaltén, Argentina. Revered for its vertical granite walls and notorious hurricane-force Patagonian storms, it is considered one of the most technically demanding alpine summits on Earth. French climbers Lionel Terray and Guido Magnone completed the legendary first ascent on February 2, 1952, establishing the historic Franco-Argentine Route.

Franco-Argentine Route
The Franco-Argentine Route on Cerro Fitz Roy is the historic first ascent line on Patagonia's most iconic granite monolith. Pioneered in February 1952 by French climbers Lionel Terray and Guido Magnone, the route ascends the Brecha de los Italianos, traverses the south shoulder, and tackles sustained vertical granite cracks up to French 6c (5.11a) and A2 aid amid ferocious Patagonian winds.
Fitz Roy Supercanaleta
The Supercanaleta on the Southwest Face of Cerro Fitz Roy (3,405 m) is one of the most legendary, direct, and imposing alpine ice lines in the world. Ascending an unbroken 1,600-metre vertical couloir of ice, snow, and mixed granite chimneys, it was first conquered in January 1965 in pure alpine style by Argentine mountaineering prodigies José Luis Fonrouge and Carlos Comesaña over two and a half days.
