Nevado de Chañi. An expedition of the Centro Andino Buenos Aires made a new route on the Nevado de Chañi (19,882 feet) in northern Argentina. Cesarino Fava, Augusto Mengelle and Felipe Frasson climbed the central spur of the north face in early October. The first ascent of the peak was made in 1901 by Hofsten and Mercado.
