Piuquenes Pass (Andes Crossing)

EXTREME // LETHAL
Full Route Report

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.

Snow Lake & Biafo-Hispar La

EXTREME // LETHAL
Full Route Report

The frozen wilderness. The Snow Lake trek is one of the world's premier high-altitude glacier traverses. Traversing the Biafo and Hispar glaciers, it covers a distance of over 120km, connecting the ancient kingdoms of Baltistan and Hunza. Snow Lake itself is a massive high-altitude ice basin (Lukpe Lawo) at 4,877m, spanning 16km in width. Surrounded by nameless granite spires and massive ice walls, this trek is a journey through a world that remains largely unchanged since the last ice age—a place of absolute silence, shifting crevasses, and monumental scale.

EXTREME // LETHAL

The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.

Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.

Full Scale Documentation
Route A // Hazard Verdict
Piuquenes Pass (Andes Crossing)
EXTREME // LETHAL
acclimatization_and_ams: Prolonged exposure above 4,000m poses a risk of Acute Mountain Sickness (AMS).
river_crossings: The Tunuyán River involves significant water volume and current strength, particularly in the afternoon.
Route B // Hazard Verdict
Snow Lake & Biafo-Hispar La
EXTREME // LETHAL
complex glacier navigation and crevasses: Both the Biafo and Hispar glaciers are highly active. Hidden crevasses, especially after fresh snow, are a severe threat.
extreme high topographical exposure: Trekkers spend over a week above 4,500m. There is zero medical infrastructure and helicopter rescue is extremely difficult and weather-dependent.
