Aconcagua, Polish Route. A Catalonian expedition under J.M. Molina that was attempting the Polish route in winter, managed to place two of its members on the summit on August 22. Skis were used from a height of 14,000 feet to some 200 feet below the summit, since the last tract was devoid of snow. Aconcagua had been ascended previously in the winter season (June to August), but this is the first ski ascent of the Polish route.
