About This Route
Dead Woman's Pass, also known as Warmiwañusca at 4,215 meters (13,828 feet), marks the highest point on the classic Inca Trail in Peru's Andes. While famous for hiking, advanced backcountry skiers tackle its steep north-facing slopes during the dry winter months for thrilling powder descents. Start from Wayllabamba camp (3,000m), skin up grassy approaches turning to snowline around 3,800m, then ascend the exposed ridge to the pass. The 1,000-meter vertical descent offers 45-degree pitches with corn snow or fresh powder, ending near Llactapata ruins. This expert-only route demands precise route-finding amid rocky outcrops and narrow couloirs. Follow Leave No Trace principles by sticking to durable snow surfaces and packing out all waste. Local conditions mirror those in nearby Ausangate range, with stable snowpack when cold fronts dominate.
Safety Considerations
Altitude sickness hits hard above 4,000m; acclimatize in Cusco for 3 days, hiking Sacsayhuaman ruins per NPS high-altitude protocols adapted for Andes. Avalanches are primary threat on wind-loaded slopes; check daily bulletins from Peru's CENEPRED and use AIARE Level 2 techniques for stability tests like compression and extended column. Hypothermia risk spikes in whiteouts; monitor weather via Windy app for katabatic winds. Terrain traps include boulder fields below snowline and cliff bands near the pass. REI experts recommend partner travel and conservative line choices. Real scenario: In 2019, a skier triggered a size 2 slab near the pass, self-rescuing with beacon but suffering frostbite; always prioritize group rescue drills.
