San Lorenzo Group, Cerro Hermoso, southwest summit. From a base camp in Rio Oro Valley, Italians Luca Maspes and Diego Fregona made what they believe to be the first ascent of Cerro Hermoso’s southwest summit, calling it “Cumbre Silvia.” They climbed a new route up the 1,000m west face on November 1 in ten hours, alpine style, with difficulties of 5.8 rock and 70° ice and mixed. On November 4 they attempted the first ascent of San Lorenzo’s northeast face but climbed only 100m (ice and mixed) before retreating amid rock and ice fall.
