Achla Valley. The Kraków expedition led by Jerzy Wala, which has been described above as the first expedition in the Munjan Hindu Kush, was also active in the Achla valley, west of Sudgul village in the Landay Sin and three miles north of Barge Matal. On July 9 Borowiec, Mošcinski, Paulo and Pytlakowski made the first ascent of Kohe Du-Sikh (17,733 feet) from the southwest. On July 10 and 11 Niewodniczanski and Wala made the first ascent of Poshta-i Tez (c. 15,250 feet) from the west up the glacier and south ridge. Paulo and Pytlakowski also explored another cirque in the upper Achla valley. This is a completely new region for climbing. It is beautiful and interesting for rock-climbing.
