It is with great happiness that David and I report the first ascent of Jobo Rinjang (6,778 meters) via the direct south face, in the Khumbu Region of Nepal, climbing alpine style over 6 days (from April 20 to April 25), summiting on April 22nd.
After a week's worth of scouting and further acclimatizing, we settled on what we determined to be possibly the only "safe" line that we could foresee doing alpine style on the entire Lunag Massif (see the last post for a full description and images of the massif). We were amazed at the near impenetrability of this group of peaks. The entire south side of the massif was a nearly all shear cliff. Added to this was a constant barrage of rock fall as it seemed there was no decent quality stone anywhere. The north and east sides were completely rimmed in hanging glaciers and careful studying revealed absolutely no safe routes. The west side of the massif sits entirely in Tibet - this might be a viable option for climbing the Lunag's, but inaccessible to us.
Amidst all this chaos, the south face of Jobo Rinjang seemed to maybe hold something for us. A swath of ice led directly up the 1,700-meter face, snaking between rock bands and two ice cliffs high on the face. This was to be our route. It was difficult to access the objective danger initially. It appeared that perhaps the right-hand and larger of the two ice cliffs drained mostly right of the ice line, while the left and smaller one would perhaps spill left. What we didn't count on as much, and which took us by surprise, was the rock fall danger from multiple rock bands across the entire face.

We packed up our kit and left base camp in Lunag (5,050 meters) on April 20th. The first part of our journey was to cross the great confluence of the Nangpa La and Lunag Glaciers, then make our way west up the Lunag Glacier to the base of the face. The total distance was over 4 kilometers of very tedious (and perhaps dangerous) rubble-filled, boulder-shifting, ice and rock maze. After many close call (and fun rides with tent-sized boulders threatening to kill us) we arrived safely at the base of the face, not that much higher than base camp (5,100 meters). Much of the sides of the glaciers are steep debris walls that have not yet reached the angle of repose, but luckily here was an easy way to get off the glacier and access the mountain.
Our first big dilemma was that it looked like there was no good place to bivy on the face until above the hanging glaciers. This was nearly 1,500 meters above us. Banking on our prior 4-weeks of acclimatization, we decided to go for it and it proved to be one of the hardest days in the mountains either of us ever have experienced.
We awoke in the wee hours of the morning and started heading up the mess of ice, snow, and rock scrambling to gain the initial ice path. Once we hit the blue ice, we started simul-climbing.

Then out of no where we heard the tell-tale rapidly spinning sound of looming death - a rock the size of a microwave went zipping past us - and we were just worried about the hanging glaciers. The rest of the climb, I kept my head back and eyes glued to the terrain above us. Several more rocks careened past us, but we were lucky enough to be spared.

Things went smoothly for several hours as we efficiently gained elevation.

As we got higher, the going got slower, mainly due to altitude and fatigue. We began to wonder if the ice would ever end. As the day wore on, the weather started changing for the worse, but we continued our ascent, and started pitching out some steeper sections. In became dark and started snowing, but finally we made a horizontal traverse right to the top of the right-hand hanger.

That video sums it up, the next morning luckily dawned clear again and we had a great day climbing the upper headwall.

A great unobstructed view of Everest, Lhotse, and Makalu:
Above our bivy, the climbing changed from ice to our favorite: steep unconsolidated snow flutings. With no real protection or belays, we carefully worked our way up.

After several rope-lengths, we pulled over onto the summit dome.
Joe coming up to the summit: (photo: DG)
Our plan at this point was to maybe get a crack at some of the other summits in the massif. But we were a full 2 kilometers from Lunag I and a long Kang Nachugo-like knife edge ridge separated us from the other peaks. We camped on the summit of Jobo Rinjang (the only real flat spot anywhere to be found) and made an attempt on the ridge the next day. I won't go into too many details of the attempt, other than to say the ridge was heavily corniced with unconsolidated snow with warm temperatures during the day, making for risky conditions. We tried some antics for an entire day and got ourselves into some funny hard terrain, but ultimately we were unsuccessful.

The next day it was time to head down. The weather was perfect, albeit too very warm, which made us nervous about rockfall on the descent. We downclimbed from the summit several pitches, until able to start V-thread rappelling in solid ice.

We made every rappel by pulling the rope through a V-thread, thus leaving absolutely no tat or garbage and no trace of our ascent on the mountain. (photos: JP)
Rappelling down the lower couloir. We made exactly 20 60-meter raps down the face before we started downclimbing again. (photo: JP)


And finally down the lower slopes: (photo: JP)
On the lower section we encountered some serious rockfall - but came out unscathed.
We made it down to the glacier by early evening and crashed out in the tent. The next morning we made our way back over the crazy glaciers to base camp in Lunag.

We hiked around a little more for some pictures, then loaded up the yaks to head out to Lukla: (photo: DG)
On the way out we stopped at some of our friend's remote homes to visit. Here is the mountain paradise of Chhule: (photo: JP)
We slowly made our way back with several stops for drinking Chang and Thungba. Eventually arriving back in Lukla for our flights back.
