Piuquenes Pass (Andes Crossing)

Following the historic path used by the Army of the Andes in 1817, this 6-day trans-Andean expedition traverses the central cordillera from Mendoza, Argentina, to the Cajón del Maipo in Chile. The route crosses two significant high-altitude barriers—Portillo Argentino (4,330m) and Paso Piuquenes (4,030m). Hikers move through a high desert landscape of volcanic rock, vast glacial valleys, and the powerful Tunuyán River. The terrain consists primarily of rocky mountain paths, loose scree on the steeper pass approaches, and high-altitude plateaus where exposure to wind and sun is constant.

Gunnbjørn Fjeld is the crown of the Watkins Mountains and the highest peak north of any Arctic Circle (3,694m). This is not a hike, but a serious high-latitude alpine expedition. Access depends entirely on specialized ski-planes landing on the Christian IV Glacier, where teams establish a base camp at roughly 2,200m. The climb is a non-technical but physically demanding glacier ascent, navigating hidden crevasses and steady 30-35 degree snow slopes. It is a world of pure white and deep blue, where the mountain's dark granite 'nunataks' pierce through an ice sheet that stretches as far as the eye can see.
