Mountaineering Safety on Regular Northwest Face, Half Dome safety guide

About This Route

The Regular Northwest Face of Half Dome offers 23 pitches of 5.12 or C1 climbing over 1,800 feet, a Yosemite Search and Rescue (YOSAR) classic since Royal Robbins' 1957 ascent. Expect sustained cracks, the Zigzag traverse, and a summit slab; thinner crowds than cables but same exposure.

Safety Considerations

Yosemite NPS analysis shows 40% of accidents from gear misuse; here, thin cracks demand precise nuts and small cams, failing which caused a 2019 fatality. Leader falls hit 25%, worsened by pumpy 5.10 slabs mid-route. Rockfall spikes post-storm; 10% deaths linked. Unroped solos risky on approach slabs. Environmental hazards: lightning on summit, hypothermia in shade (four NPS-documented cold deaths). Plan per REI guidelines: start pre-dawn, off by noon. Scenario: 2021 party caught in thunderhead, sheltered under chockstone, rescued via short haul. Leave No Trace: pack out all waste, use wag bags above 10,000 feet equivalent exposure.

Essential Gear

Carry Black Diamond HB nuts, Metolius Micro Stoppers, #00-3 cams, Sterling 9.5mm ropes (60m double), Black Diamond Oz headlamp, and SPOT Gen4 messenger. REI insists on approach shoes like La Sportiva TX4 for subdome scramble.
