British Expedition to Cordillera Vilcanota (Peru) and Cordillera Real (Bolivia)(Alpine-stvle Andean)

Stephen Venables and David Wilkinson succeeded in a dramatic first ascent of the 700m W face of Jatunhuma T ('Tres Picos'). An ice-cave bivouac near the summit was followed by a complicated descent round the back of Jatunhuma II and Ill. In the Sorata massif of the Cordillera Real, together with other members of the party, they achieved the first ascent of the S face of Llihirini (5,970m), the first ascent of the NE couloir of Ancohuma (6,427m), following the ESE ridge to the summit, and finally an interesting ascent of Illimani (6,487m) by W spur and W face.
