Edinburgh University Mountaineering Club Apolobamba 1997
This group set out to explore the Sorel Oeste group, and climb as many new routes as possible. Experiencing good weather throughout, they succeeded in making new routes on the W Face of Sorel Este, 5,471m, the NW Face of Katantica Oeste, 5,630m, and the S Ridge of Sorel Oeste, 5,641m. They also made the first traverse of the ridge from south of Palomani all the way north to just below Chaupi Orco, reaching a maximum height of 6,400m on Illimani.
