Szczegółowy podział

Ama Dablam at 6,812 m is climbed via the Southwest Ridge route, established by the 1961 New Zealand team. The 28 to 32 day expedition includes 12 trekking days to base camp at 4,600 m and 14 to 18 climbing days on the mountain. The route has 4 camps: Camp 1 at 5,700 m, Camp 2 at 5,950 m, Camp 3 at 6,300 m, and the summit at 6,812 m.

The 4 fixed rope sections require specific techniques. The Yellow Tower at 5,800 m is a 30 m vertical granite pitch graded IV 5.7. Fixed ropes are 11 mm dynamic and anchored at 3 to 4 m intervals. The Grey Tower at 6,000 m is a 40 m overhanging pitch graded IV plus 5.8. The Mushroom Ridge at 6,100 m is a 200 m mixed snow and rock traverse.

Co wpływa na odpowiedź

Prior climbing experience is the biggest factor. Climbers who have completed a 6,000 m peak like Mera Peak have the altitude base but lack the technical rock and ice skills. Climbers without grade IV rock experience need 4 to 6 weeks of pre expedition training.

Rope teamwork is the second factor. The fixed rope sections are climbed in teams of 2 to 3 with a guide. Each pitch takes 30 to 90 minutes. Weather windows are the third factor. The summit push needs 3 to 4 consecutive days of stable weather with wind below 30 km per hour at 6,800 m. Acclimatization is the fourth factor. Climbers need 2 rotations to Camp 2 at 5,950 m before the summit push.

Wskazówki dotyczące rezerwacji

Book a 30 day expedition with an operator who has 10 plus Ama Dablam expeditions in the past 5 years. Confirm the operator provides 2 climbing guides per 4 climbers and a satellite phone for the summit push. Carry your own jumar ascenders, harness, helmet, and ice tools that you have trained with. Rent fixed ropes, ice screws, and pitons from the operator. Schedule 2 days of technical training at base camp before the first rotation to Camp 1.

Porównanie z alternatywami

Mera Peak at 6,476 m requires no technical climbing skills, just basic glacier travel with ice axe and crampons. The 18 to 20 day expedition costs USD 2,800 to USD 4,200. Island Peak at 6,189 m has a 100 m WI2 ice headwall requiring jumar technique on fixed ropes. Lobuche East at 6,119 m has 200 m of 45 degree snow and ice climbing.

Częste błędy, których należy unikać

Climbers often attempt Ama Dablam with only Mera Peak or Island Peak experience and no grade IV rock climbing background. The Yellow Tower and Grey Tower pitches require specific jumar technique that takes 2 to 3 days to learn at base camp.

A second mistake is using new or unfamiliar gear on the summit push. Jumars and ice tools should be broken in on the 2 acclimatization rotations.
