Fitz Roy Attempts. Yugoslavs Boris Simoncic and Matevž Lenarcic attempted the American route on Fitz Roy in January but were driven back by the weather 350 feet from the summit. They then attempted the Super Couloir twice and the French route and again were driven back all three times. An attempt on the Aguja Guillaumet also failed 250 feet from the summit. Such bad weather is unfortunately all too typical in Patagonia.
