Cerro Yana de Colac, Cerro Ventanilla and Cerro Yana Pucara, First Ascents. In 1997,I visited the two more accessible districts of the Cordillera Central, located inland from Lima. I first traveled to the Cordillera de la Viuda. After traversing four high passes while vainly searching for some elusive ice peaks shown on the official maps, I made the first ascent of Cerro Yana de Colac (5028m, easy rock) on May 30. It is located eight kilometers west of the village of Shanglar. A week later, I visited the second district, Cordillera de Cascacocha. On June 10 and 12 respectively I made the first ascents of Cerro Ventanilla and Cerro Yana Pucara, both 5000 meters high and both located at the head of the Ventanilla stream. After a failed attempt on the rocky tower of Cerro Ajutanca (5050m), I returned to Lima.
