Cordillera Blanca. Dr. Duane Ewers made two ascents in the Cordillera Blanca, the exact identification of which is not altogether certain. With François Mégard of the French Embassy in Lima, and the Peruvian porter, Eugenio Angeles, he climbed a peak at the head of the Quebrada Ishinka to the south or southwest of Palcaraju. This may have been a first ascent or may have been the fourth ascent of Palcaraju Oeste (West). With Angeles and another Peruvian porter, Dr. Ewers made what appears to be the second ascent of Pisco Este. The Swiss, Max Ehrensperger, Max Riegg and Victor Rutishauser, joined Dr. Ewers on two unsuccessful attempts on Huascarán, but they were turned back because of bad weather.
