Campanile Esloveno, Northeast Face, and Torre Astilla, Catedral Group, Bariloche. Dinko Bertoncelj of the Club Andino Bariloche and José Luis Fonrouge of the Centro Andino Buenos Aires made the first ascent of the northeast face of the Campanile Esloveno, a huge granite tooth about 6900 feet in altitude in the Catedral group just south of Bariloche. Bertoncelj made the first ascent of this peak with Francisco Jerman by its southeast ridge in 1952. Fonrouge made the fourth ascent last year by the same route. This new route is probably the most difficult rock climb yet made in the Argentine, much being grade VI. The climbers surmounted a series of dihedrals, overhangs and chimneys, rising about 500 feet vertically. On February 17, 1960, they climbed the first half in five hours and descended, leaving fixed ropes. The next day they completed the ascent in another five hours. They used 18 pitons, two wedges and four expansion bolts. On February 16 the same team, accompanied by Anselmo Weber, had made the first ascent of the Torre Astilla (Splinter Tower) between the Campanile Esloveno and the main tower of the Cerro Catedral.
