Climb leader and author of the description — Zaretsky Ivan Approach: Both routes start from Molodyozhny pass. You can ascend to the pass from the side of Mramorny lake. From the lake, a trail goes towards the pass, which leads to a scree slope. You will have to ascend via a talus field, bypassing the "sheep's foreheads". This path to the pass is:

• the shortest,
• not the easiest to ascend,
• not the safest to descend. From Mramorny lake, you can also reach Molodyozhny pass via Kursanov pass. From the lake, a trail leads to Kursanov East pass. Then, from the pass, the trail goes along the ridge towards Molodyozhny peak. From Kursanov West pass, the trail, going along the slope, leads to Molodyozhny pass. This path is longer, but it mostly follows an obvious trail.

1B to Uchiteley peak:

The route starts from Molodyozhny pass. From the pass, the route follows a trail that, bypassing the summit on the right, leads to the ridge. The highest point of the ridge is the summit. Descent is done via the same route.

1B to Molodyozhny peak

The ascent leader and author of the description is Zaretsky Ivan Approach: Both routes start from the Molodezhny pass. You can ascend to the pass from the Mramorny lake side. From the lake, a trail leads towards the pass, which ends at a talus slope. The ascent is via the scree, bypassing the "ram's foreheads". This path to the pass is:

• the shortest,
• not the easiest to ascend,
• not the safest to descend. From Mramorny lake, you can also reach Molodezhny pass via Kursanov pass. From the lake, a trail leads to Kursanov East pass. Then, from the pass, the trail follows the ridge towards Molodezhny peak. From Kursanov West pass, the trail, going along the slope, leads to Molodezhny pass. This path is longer, but it mostly follows an obvious trail.

16 to Uchyitel peak:

The route starts from Molodezhny pass. From the pass, the route follows a trail that, bypassing the peak on the right, leads to the ridge. The highest point of the ridge is the summit. Descent is via the ascent route.

Ascent from the Tagiltsev Pass, route 1Б cat. diff. (Fig. 17). The Koptau peak is located in the New spur of the Trans-Ili Alatau ridge between the Tagiltsev and TEU passes. The path to the Koptau peak from the Talgar alpine camp goes along the trail up the gorge to the Green Glade, then you need to:

• cross two streams flowing from the Shokalsky Glacier;
• approach the lake at the tongue of the North TEU Glacier. Here is the overnight stay. From the bivouac site to the Tagiltsev Pass. The exit to the pass is via a couloir with small and medium scree. There are snow patches. Steepness is 30–35°. At the bottom, the couloir is wide, with a rocky ridge in the middle. In the middle part, the couloir is divided into three narrow couloirs. It's better to go along the left one, which is wider and less prone to falling rocks. After 40–50 m, the pass point is reached. From the Tagiltsev Pass, follow the snowy ridge to the south to a large inclined gendarme. The ascent to the gendarme is in its middle part. Move with caution: the rocks are destroyed. Turn right and exit to an inclined platform. Descend from the gendarme to the left, initially along the second inner corner for about five meters. Then proceed to the second destroyed gendarme, which is bypassed on the left. The further route follows the snowy ridge. There are cornices on the left, and a slope turning into an ice wall on the right. The ridge has three height drops. After an hour of movement, the summit is reached. Descent is via the ascent route. The entire ascent from the initial bivouac takes 7–8 hours.

Location, History of Ascent, and Approach Routes

Peak named after I. V. Kurchatov is located in one of the spurs of the Left Talgar river basin and closes the Rusakova river gorge, which flows into the Left Talgar river (see map). The peak is clearly visible from the Kuldzhinsky tract on the segment between Malaya Stanitsa and Almaty tobacco farm, and has an impressive appearance. Its approximate height is 4200 m. It is not surprising that, being unclimbed, it attracted the attention of mountaineers from the Institute of Nuclear Physics of the Academy of Sciences of the Kazakh SSR. From the scientific town of INF, its summit stands out with its strict outlines against the background of surrounding peaks (photo 1, 2). Therefore, in August 1966, a group of mountaineers from INF consisting of:

• Saprykin V. D. — Master of Sports
• Il'inykh A. M. — 3rd sports category
• Gubanova A. M. — 3rd sports category
• Mukhamedshina D. M. — 3rd sports category accompanied by an observation group, made the first ascent to the unnamed peak 4200 m. Paying tribute to the achievements of the outstanding Soviet physicist I. V. Kurchatov (1903–1960), the mountaineer-physicists, as the first ascenders, named the conquered peak after I. V. Kurchatov.

Mestia route via the Southwest Ridge, Category 1B

Route Description:

From the "Djailyk" base camp* past the "Ullu-Tau" recreation center and further along the trail along the right (orographically) bank from Adyr-Su to the moraine rises to the left of the Adyr-Su glacier tongue. The first of these has Mestian overnight stays. Climbing to the next rise, we reach the glacier and cross it in the direction of the large hitching post on which the Mestian hut is located; we go around the hitching post on the left and climb onto it. There are small crevices under the hitching post. From the Mestia Hut, we ascend a steep firn slope, and to the right of the rocky ridge, we reach the glacier. The path continues along the glacier, which is usually covered with a thick layer of snow. Large glacier crevices are bypassed on the right as we proceed. Further, after a steep ascent, we again emerge onto a large firn plateau, along which we move in the direction of the Mestia Pass. From the Mestia Pass, we turn left and move across the vast firn plateau towards the snow pyramid of Mestia-Tau. Crevices are possible on the left as we proceed. Descent is via the ascent route. The median moraine of the Adyr-Su glacier
