Aguja Guillaumet. After climbing Aconcagua by both the normal and the French south-face routes and five attempts on Fitz Roy driven back by bad weather, our Basque expedition reached one summit. In unstable weather in February, J. C. Tamayo climbed Aguja Guillaumet via the northeast ridge from a camp on the Paso Superior.
