When everyone is ready and ABC is established, we will strike base camp and head up the Barun Glacier, passing the impressive West Face of Makalu, until we reach the point where the West Pillar Route of Makalu descends onto the glacier. Here we turn northwards and continue on Glacier moraine up to Advance Base Camp, which is located on a rocky promontory at 5,700m. Sheltered from the wind and from any rock fall, this camp will become home for the next few weeks. It can be very cold though, so if you intend to bring 2 sleeping bags (one for the mountain and one to leave in ABC), make sure that both are rated 5 seasons. It takes about 7 hours to make the journey from base camp to ABC.
After our important Puja we can then take our first foray onto the mountain and walk up to the Chago Glacier that gives us access to Camp 1. About 45 minutes from camp, we will establish a crampon point where we can leave our mountaineering boots and climbing equipment, which are essential for travel to Camp 1 and above. Our Sherpas will be busy fixing ropes on the glacier to ensure our secure passage and carrying loads to make sure our first camp is established.
Once the leader is comfortable that the team members are acclimatized, we will make our first visit to Camp 1 (6,347m). From the crampon point, the route takes us across some crevassed terrain on an easy-angled glacier to a steep wall which we ascend for 150m on a fixed line. From the top of the wall it is a short walk to camp along the flat plateau, situated on the Chago Glacier. On the first visit, the journey to Camp 1 will take around 5 hours, but as we become further acclimatised, this time will be reduced. Later on in the expedition, some team members may decide to move straight through to Camp 2 at 6,670m, rather than stop at Camp 1 for the night. We will want to make this journey early in the day, as it can get very hot on the glacier in the afternoon.
The route from Camp 1 to Camp 2 involves some easy-angled climbing through beautifully sculptured glacier terrain. Winding around the huge crevasses care is required to follow the correct route. Fixed ropes will be put in situ across crevasses and snow bridges. Tucked under a serac band, Camp 2 has fantastic views of Everest, Lhotse and Barunste. Once acclimatized, the trip to Camp 2 should take around 2 hours from Camp 1 or 6 hours from ABC.
Once we have acclimatised to sleeping at Camp 2 the leader will decide when it is time to explore the route up to Camp 3 onto the Makalu La. This is very much a landmark in the expedition and is one of the most technical sections of climbing on the mountain. Before we venture onto the climb between camps 2 and 3 the Sherpas will have ensured that the fixed lines are in place. Climbing to the Makalu La involves movement over rocks covered in ice and snow to an angle of 50 degrees. From Camp 2 we climb the easy-angled glacier to a height of 6,950m from where the rocks start and continue for 300m to 7,250m. At this point there is a snowfield to cross, which can be subject to avalanche danger and in deep snow it will certainly test your strength and determination. After a further 200m the next section of the route is interspersed with sections of blue ice and rocks, which provide interesting climbing. At the top of the Makalu La, we will cross the glacier for a further 200m to where Camp 3 is located at 7,400m. The decision to fix camp and to ascend to the Makalu La is very weather dependent. The jet stream winds can scream across the La, dipping temperatures to well below minus 30 degrees and can destroy any camps that have been established. Consequently, careful consideration at this stage of the expedition is essential for a safe ascent and also further progress on the mountain. Some members may wish to use oxygen on the final section to reach the Makalu La. Depending on temperatures, team members may need to wear their down trousers and jacket from Camp 2. We will also be aware of how much gear to carry to Camp 3 on the La, as it is difficult descending from there with very heavy loads.
From Camp 3, Camp 4 is established at 7,600m, which is the launch pad for the summit. Tent spaces at this altitude are limited, so is the time you would want to spend here. Reaching Camp 4 from the Makalu La involves traversing a large, flat glacier, with many hidden crevasses, towards the gigantic North Face of Makalu. Camp 4 is perched in a serac band protecting it from avalanches from the slopes above. It takes only 3 hours to climb from Camp 3 to Camp 4, the only feasible resting spot before the summit.
From Camp 4, the route traverses steeply across an ice band, before coming to a huge snow ramp, which leads to a heavily crevassed plateau. After crossing the plateau, the bottom of the French Coulouir is reached. This is a 300m high shallow gully, bounded by granite buttresses, providing excellent mixed climbing. Though never too steep, the couloirs is climbed with interest to a height of 8,350m, where the summit ridge is revealed. This flattish shoulder of ice leads to some very exposed summit towers, which are negotiated with great care, to get to the small summit area of Makalu – the 5th highest point on the planet!
Summit day is a very long and demanding climb, with an equally difficult descent returning the way you ascended back to Camp 4 and preferably all the way to Camp 3. At 7,400m, Camp 3 is still very high on the mountain and you must retain enough energy and concentration to negotiate the difficult descent, abseiling over technical ground from the Makalu La to Camp 2 and finally back to ABC. Once back at ABC you can relax and know that you have attempted and either succeeded or not on one of the most beautiful mountains in the world.
