on our way


On our way to Cerro Bonete, 5,052 m.
Scramble: RT 7.5; 4.5 up from base camp. Cerro Bonete grants a fantastic viewpoint of Aconcagua's west face. It is a side trip offered with INKA's extended route package to facilitate acclimatization. Including this ascent in the itinerary is a wise choice; giving your body time to acclimatize increases the chance of a successful attempt on Aconcagua and will make the climb less strenuous. For this hike, we didn't start too early; we waited for the sun's rays to shine onto base camp to warm the cold morning air. After a good breakfast, we began hiking slowly, taking many breaks. Although the alpine scenery is similar to the Canadian Rockies, there are striking differences. The sheer size of the mountains, combined with the absence of sub-alpine terrain and the forest below in the valleys, are reminders of the altitude and dry environment of the Andes. Also, trekking through the numerous fields of penitentes was a first for me; those snow formations commonly found above 4,000 m., in areas with very low humidity, low temperatures, and lots of solar radiation, aren't usual back home. The upper mountain was delightful, granting some easy scrambling; I felt right at home, travelling like a cat. We stayed at the top long enough to have lunch and take lots of pictures; lucky for us, the wind was light. Returning was a hoot! We flew down the upper mountain's long scree slope as far as we could. After regrouping, we resumed our speedy descent back to camp. That evening, my appetite returned, and my slight headache vanished while I relaxed, drinking copious amounts of water.
