British Cordillera Oriental 2005
Although the Cordillera Oriental is relatively easy of access and the majority of its peaks are of moderate height, it is one of the lesser-visited areas of Peru. However, the vulnerability of a two-man team was brought home to this pair when Riley injured his back soon after arriving in Peru in May, forcing him to take a prolonged rest. Fortunately he recovered sufficiently to allow a return to the mountains three months later, when they climbed a new route on Nevado Nausacocha (c5,150m) and several other previously unclimbed peaks.
