Cordillera de Quimsa Cruz. In June, I made two forays from La Paz into this range south of Illimani. In the first, I attempted the west side of Nevado Vila Collo (5400 meters) but did not scale the last 200 meters of ice polished by wind and drought. I also entered the Huallatani and Laramcota Glaciers in search of routes to peaks, but the drought of the last several years had altered the surface of those glaciers. In my second campaign, I reached the mining settlement of Viloco on the northeast side of the range. On June 26, by the north side and east ridge I made the first ascent of P 5160 (16,929 feet), which lies east of Cerro Negro; I named it Jisca Jaque (“Small Rock Peak” in Aymara) The rock was excellent. On June 29,1 climbed to the gap between Nevado Cori Chuyma and its western neighbor, P 5300 (17,389 feet), a long ridge with many points. I traversed the two highest summits, located at each end of the ridge and called it Curumiña (“Precipice Peak” in Aymara.) Snow storms in early July blocked roads to the mining villages and prevented further climbs.
