Cordillera Raura. The Peruvians Terencio Jiménez and Máximo Luna, of the Club Andinista Huarancolca, of Churín, and I, made an ascent of Nevado Yanco (16,437 feet) on July 28. We approached the peak via Raura mine and the lake of Niño Perdido, and then to the top via the Huambara Hargrashga glacier.
