BC at Hillary BC area near Tangmar
ABC at normal BC site
High point at NW Ridge.

BC was pitched on 23 April at 4850m near Tangmar in the Hillary BC area at a grassy spot pleasant for resting. Two days later, they occupied teh normal BC site at 5700m. Then they immediately went up the normal NW Ridge route to acclimatize before going to climb their chosen line on the West Face. On the 26th they moved up to 6300m on the Chago Glacier and returned to BC the same day. On the 30th they went up to 5795m and on 1 May to 6682m and back to BC that day.

Now they divided into two groups. On 5 May House and Prezelj went onto the Chago ridge, which borders the west side of Chago Glacier and in three days with two bivouacs traversed the ridge from its southern end to point 6350m on the ridge (by the Schneider Khumbu map) and down to the tent they had left at ABC (5700m).

The other group, Blagus, Lindic and Lorencic, went up onto the Chago ridge and bivouacked there at about 6000m. The next day they took the shortcut over to the normal route at 6700m. On the 7th they moved to the Makalu La at 7400m, then down to 6700m. On the 8th they descended to 5650m and BC.
