Nevado Huallanca, Koso. Between the cordilleras Blanca and Huayhuash is the small Cordillera Huallanca. Although it does not rise above 6000m, it offers beautiful mountains with glaciers and rocks. David Rodriguez Lopez climbed the mountain known as Cumbre de los Burros or Nevado Huallanca (5470m), the highest summit of the Cordillera Huallanca. The route, completely on glacier, starts near the west side of Collado de los Burros, next to a small lake. The route is approximately 500 meters long and is graded MD, with 70-85-degree snow and ice. The descent was by rappelling the route. The name of the route is Koso.
