One of the most beautiful place of the Pamir Mountains is the snow- and ice-covered Trans-Alay Range. To the south-east there is a 4000m high plateau with 380km² of Lake Karakula, to the south-west – the little-explored Pamir mountains Saukdara and Beleuli Ranges. Information about this area was available to us only from the materials of the German-Soviet Pamir expedition of 1928, when the photogrammetric relief was taken. We made sure that these old maps were accurate. The main goal of the beginning of this montain hike was this little-known mountain area exploration, where we planned to find new passes, which we also successfully made – naming the new first ascent crossings over the Beleuli ridge as Baltika 88 Pass (2B 5260m) and across the Saukdara ridge as the Rozenstrauha Pass (2B 5470m). In the Saukdar valley, we took the food reserves brought from the side of Lake Karacula across the Zulumart Range and continued the route through much higher mountains. Overcoming the difficult West Wali icefall in the blizard, we climbed the W Wali Pass (3B 6300m), where we had our first high-altitude overnight stay. The next day we traversed the Dzerzhinsky Peak (6717m) in the direction of the Dzerzhinsky Pass (3A 5700m), from where we descendid along eastern ridge on the Koman Glacier. The rest day was followed by the ascent to our most technically complex and also the first ascent Lāčplēsis (“The Bear-Slayer”) Pass (3A* 5580m). We ascended a difference of 1380 meters in height in one day climbing cliffs and ice with an average slope of 50°. After descending through the icefall on the Lenin Glacier, we ascendid to the Lipkin Rocks (5200m), which is a traditional place to spend the night before climbing to the top of Ibn Sina. After another overnight stay on a ridge at an altitude of 6504 m, we ascendid to the top of Ibn Sina (former Lenin) Peak (7134 m). After descending to the upper circus of the Great Saukdara Glacier, we crossed the KKT 20-year Pass (2B 5940m) and, crossing the cracked October Glacier covered by giant calgaspores, we reached the place of “paradise accommodation”. An unpleasant surprise awaited us here. The food reserves left on the glacier at an altitude of 4900m and burried with rocks had been found by a bear, which had apparently followed many kilometers along our footsteps from the valley and had destroyed our food along with the birds, scattering stones and tearing packages. As a miracle, a bottle of cognac, whole, only slightly scratched with a bear’s claws, was left to celebrate Janis L birthday. Fortunately, the fuel reserve was not damaged and during the remaining five days, we survived by drinking plenty of melt water from the snow and eating leftover food. In two days we climbed to the Kizil Agin Pass (3B 6540m) and traversed the Kizil Agin Peak (6683m) along the northern ridge with an overnight stay at 6020m, after then we descended on the Spartakiad Glacier. We crossed the moraine of the Korzhenevsky Glacier, climbed to the Obruchev Pass (2B 5040m) and descended into the Alay Valley. Overall, the expedition was very interesting, technically complex and required excellent physical condition. In twenty-five days we walked 182 kilometers, crossed nine passes, climbed the top of Ibn Sina (former Lenin) Peak (7134 m), traversed the peaks of Dzerzhinsky (6717m) and Kizil Agin (6683m), spent four nights over 6000m, the total elevation during the montain hike was 14.4 kilometers. With this hike we participated in the USSR mountain hiking championship, where we won silver medals.
