Cordillera de Quimza Cruz, Los Cuernos del Diablo. On April 11, Pete Grosset (UK) and I climbed a new route on Los Cuernos del Diablo (5271m). The route consisted of six pitches (250 meters) on solid granite and followed a straight line directly up to below the northeast horn. It finished on the upper two pitches of the original “Classic” route of the 1987 Bolivian-German expedition. The overall grade of the route was 5.10b, with excellent protection following connecting cracks.
