Official Expedition Narrative & Archival Record
For centuries, the marble spire of Khan Tengri ('Lord of the Spirits', 7,010 m) was regarded across Central Asia as an unapproachable citadel of stone and ice. In 1929, Ukrainian physician and geographer Mikhail Pogrebetsky launched a multi-year campaign backed by the Ukrainian Physical Culture Council and the Red Army to achieve the first ascent. After two reconnaissance expeditions in 1929 and 1930 mapping the labyrinth of the South Inylchek Glacier, Pogrebetsky returned in the summer of 1931 with an elite team. Braving sudden glacial lake outburst floods from Lake Merzbacher and dodging massive serac avalanches from Peak Chapaev, the party forced their way up the Semenovskiy Glacier névé to establish Camp 3 on the West Col (Chakan-Tau) at 5,900 metres. On September 11, 1931, under freezing azure skies, Pogrebetsky, Boris Tyurin, and Austrian climber Franz-Josef Zauberer climbed the sheer, polished marble slabs and brittle snow crest of the West Ridge. At 2:00 PM, battling intense hypoxia and bitter winds, all three climbers stepped onto the sharp summit crest at 7,010 metres, planting the red flag of Ukraine and completing the highest summit ascent in Soviet history at the time.

Ascent Route & Topography

Khan Tengri West Ridge & Pogrebetsky Route
The West Ridge Pogrebetsky Route is the premier classic route on Khan Tengri (7,010 m), leading from the South Inylchek Glacier up the Semenovskiy Glacier to the West Col (Chakan-Tau, 5,900 m) and ascending the exposed western marble ridge. First climbed on September 11, 1931, by Mikhail Pogrebetsky, Boris Tyurin, and Franz-Josef Zauberer, the route involves sustained climbing on steep snow couloirs and technical marble rock bands above 6,700 metres. The route requires fixed-rope jumaring, rigorous acclimatization, and exceptional endurance against high-altitude hypothermia.
Target Objective Peak
Khan Tengri / Lord of the Spirits
Khan Tengri is a breathtakingly symmetrical, marble-stratified pyramid rising to 7,010 metres (22,999 ft, including summit ice cap) in the Tengri-Tag range of the Central Tien Shan, straddling the borders of Kyrgyzstan, Kazakhstan, and China. Revered in ancient Tengrism as the sacred 'Lord of the Spirits' and famous for its fiery pink glow at sunset, the peak is one of the premier challenges of high-altitude mountaineering. First conquered on September 11, 1931, by a Ukrainian expedition led by Mikhail Pogrebetsky via the West Ridge, it was the scene of an epic survival climb in 1936 by the Abalakov brothers.
Featured Expedition Climber

Mikhail Pogrebetsky
Mikhail Timofeyevich Pogrebetsky was born in 1892 in Yalutorovsk, Tobolsk Governorate, Russian Empire. Educated in Saint Petersburg, Pogrebetsky relocated to Ukraine where he worked as a physician, geographer, and alpine educator. During the 1920s, Pogrebetsky became fascinated by the mythical, unclimbed marble pyramid of Khan Tengri (7,010 m), situated in the most inaccessible depths of the Central Tien Shan. Between 1929 and 1931, Pogrebetsky organized three systematic expeditions sponsored by the Ukrainian Council of Physical Culture and the Red Army. Penetrating the untracked Inylchek Glacier by horse pack-train and on foot, Pogrebetsky mapped complex glacial tributaries, braved sudden river surges, and analyzed the avalanche-raked walls of the Tengri-Tag range. In 1931, he identified a viable line of assault up the Semenovskiy Glacier to the West Col (Chakan-Tau, 5,900 m). On September 11, 1931, alongside Ukrainian climber Boris Tyurin and Austrian alpine specialist Franz-Josef Zauberer, Pogrebetsky breached the steep marble slabs above 6,700 metres and stood atop Khan Tengri. It was the highest summit ever scaled in Soviet history at that time. Pogrebetsky went on to author Three Years of Struggle for Khan Tengri (1935) and founded the Ukrainian Alpine Club in Kharkov, training generations of mountain rescue specialists. He died on August 16, 1956, celebrated as the pioneer who opened the Celestial Mountains.
