Lumba Sumba Peak
Lumba Sumba (5672m) is located in Eastern Nepal, and forms the watershed of the Arun and Tamor river systems. The approach was by air and Jeep to Taplejung, and 11 days in the approach and setting up base camp. The team found a hidden couloir which gave them access around the right hand side of a glacier to a steep snow slope leading to the North Ridge. This was followed to the summit in mixed conditions up to grade III. Only two days were needed on the mountain, and five of the six climbing members of the expedition summited. There was a daily pattern of thunderstorms or snow showers in the afternoons. There were four days when this did not occur, two of which were the days on the mountain.
