Route Description

R0–R1 (when ascending from Gebi valley): The path from the Western side is easier to navigate and access the Northern ridge. From the overnight stays at the bottom of the valley, we head East, ascending the Western slope of Chirh ridge. We need to go up to the right along the scree slope, orienting towards the right edge of the central part of Chirh ridge, to the rightmost standalone tower - this is at 3505 m. There are still a number of rock gendarmes to the right of it, but they are lower in height. Along the scree couloir, and in the upper part - along the rocks on its right side, we go up towards the col between the peaks of Ev. Goluba (3503 m) on the left and 300 years of St. Petersburg (3505 m) on the right. Before reaching the col, we divert to the right along rocky ledges and walls between them onto the rocks to the right of the narrow couloir; and exit onto the Northern ridge of peak 3505 m. The entire section is about 900 m. From the overnight stays, it takes 3-4 hours. R1–R2: Along the Northern ridge to 3505 m, mostly on its right side, ascend 20 m along rocks of 2nd category difficulty. To the right of the narrow ridge:

• traverse of 4th category difficulty; 70°; 2 m. After that, another 25 m; 1-2 category difficulty, and ascend to peak 3505 m - 300 years of St. Petersburg. The entire section is about 50 m; 40-50°. There are no signs of human presence on the summit. The summit is a good panoramic point. Descent is via the ascent route.
