Central Council of the Zenit Sports Society Protocol No. 396 dated April 15, 1975 5A first ascent (daib) AKTASH — 4937 m VIA THE WESTERN EDGE (first ascent) Naumov A.F. Master of Sports

Ascent via the North Ridge

The summit of Ak-tash is located in the northwestern spurs of the Alay Range, in the upper reaches of the following glaciers:

• to the southwest — Dugoba,
• to the northeast — Ak-Tash,
• to the northwest — Dugoba-Shigou. The Ak-tash summit massif consists of heavily fragmented granite and limestone rocks.

Day One

From the "Dugoba" alpine camp, we proceed along the Dugoba River valley to the confluence of the Ak-Tash and Ulitor rivers (2 hours). At the confluence, the trail forks; the further path lies along the left orographic bank of the Ak-Tash River, bypassing a pronounced rocky massif on the right. The trail leads to a green meadow; after crossing it, we descend to the Surmetash River, and then, traversing the talus and grassy slopes above the left bank of the Ak-Tash River, we reach a canyon-like steep descent to the river (3–3.5 hours from the confluence).
