In 2018, an expedition team failed on a variety of organizational issues. The bivouac was temporarily stored at an altitude of 4000 meters to complete the mission a year later with helicopter support. In October 2019, a 15-member team returned to Kathmandu. Due to the large amounts of tools and equipment, the project participants initially chartered a bus there. With this, they traveled for about twelve hours from the Nepalese capital to the Naa Valley, near the Tibetan border. From an altitude of around 1300 meters, the trek then marched on foot for about a week to the bivouac setup point in the Rolwaling Valley. The team, at times accompanied by up to 25 Nepalese porters, had to overcome almost 4000 meters of elevation. To avoid the onset of altitude sickness, the stages were deliberately kept small. This allowed them to gradually acclimatize to the altitude. The sleeping altitudes also did not exceed a difference of 300 to 400 meters per day.
