In 2018, an expedition team encountered various organisational challenges. The biwak was temporarily stored at an altitude of 4,000 metres to enable the mission to be completed one year later with helicopter support. In October 2019, a team of 15 people returned to Kathmandu. Due to the large quantities of tools and equipment, the project participants initially chartered a bus. The journey from the Nepalese capital to the Naa Valley, near the Tibetan border, took around twelve hours. From an altitude of approximately 1300 metres, the trail then continued on foot for about a week to the location where the biwak was constructed in the Rolwaling Valley. The team, occasionally accompanied by up to 25 Nepalese carriers, had to ascend nearly 4,000 metres in altitude. To prevent altitude sickness, the stages were deliberately kept short. This allowed them to acclimatise to the elevation gradually. The sleeping altitudes were also spaced no more than 300 to 400 metres apart per day.
