South America, Peru, Cordillera Blanca, Cashan Este, Mathi Matias

Cashan Este, Mathi, Matias. In July 1998 I departed from Olleros and walked toward Rurec's Quebrada (creek), before arriving at Tararhua Lake (4400m), where I set up my tent. From there I went to the southeast face of Cashan (5723m). I climbed in a couloir, to the right of a buttress that passes through the center of the face. I surmounted a section of 75-80-degree verglassed rock below a serac barrier. After surmounting a bergschrund I traversed to the left across a snow slope that took me to the southeast ridge. I crossed the ridge and continued on the 70-degree southwest face to the summit. I called the route Mathi, Matias (500m, MD-, 70-80 degrees). Descent was via the northeast ridge and the crevassed southeast glacier. It took all night, and I came back to camp early the next morning.
