Fitz Roy, Argentine Route on Southeast Buttress. Austrians Rudi Mayr and Robert Purtscheller repeated the Argentine route on Fitz Roy a few days after Galen Rowell, from November 5 to 18. They noted, “We had good weather, much ice in the cracks. Finally when we were heading for the summit, a strong wind came up. It took us only 12 hours from the Brecha de los Italianos to the summit.”
