About This Route
After cresting Dead Woman's Pass, the Pacaymayo Valley (3,600m) offers intermediate-to-advanced skiers a 800-meter bowl-to-valley descent on the Inca Trail's eastern flanks. Access via skinning from camp at Pacamayo, climbing open bowls toward Runkurakay ruins. North aspects hold dry powder in July; south faces corn snow by afternoon. Navigate ancient Inca paving hidden under snow, ending at valley floor streams. This route connects to Phuyupatamarca pass, blending cultural immersion with big-mountain lines. Respect trail closures; obtain Inca Trail permits and backcountry extensions from Peru's Ministry of Culture. Snow quality rivals Valle Nevado but wilder, with alpenglow views of Salcantay glacier.
Safety Considerations
Wind slab avalanches form post-storm; perform snowpit profiles per American Avalanche Association standards. Acute Mountain Sickness (AMS) symptoms like headache demand immediate descent; use acetazolamide prophylactically after doctor consult. Crevasse-like bergschrunds rare but possible in hanging snowfields; probe ahead. Lightning storms brew afternoons; summit by 10am. REI avalanche courses stress beacon proficiency. Scenario: 2022 group navigated whiteout using GPS tracks from Gaia app, avoiding 30m cliff; always carry redundant nav.
