Official Expedition Narrative & Archival Record
For decades, the Karakoram mountains in Pakistan had resisted every winter ascent due to extreme sub-Arctic latitude, temperatures plummeting to -50°C, and winter jet stream storms far more brutal than the central Himalaya. In January 2011, Italian Simone Moro, Kazakh Denis Urubko, and American photographer Cory Richards arrived on the frozen Baltoro Glacier. Operating in lightweight alpine style without high-altitude porters or supplemental bottled oxygen, the trio established Base Camp at 5,100 meters. Navigating the treacherous Gasherbrum icefall riddled with yawning crevasses, they established Camp I (5,900m) and Camp II (6,500m) under unrelenting blizzards. When a brief weather lull presented itself at the end of January, they pushed up the Southwest Ridge. On February 2, 2011, climbing in temperatures below -45°C with severe frostbite threatening their extremities, Moro, Urubko, and Richards reached the 8,035-meter summit of Gasherbrum II at 11:30 AM local time. Their triumph marked the first winter ascent of an eight-thousander in Karakoram history. During their descent, a colossal powder avalanche swept over all three climbers near Camp I, completely burying them; by a miraculous stroke of fortune, they dug themselves out of the snowdrifts and reached Base Camp alive.

Defined Alpine Terminology & Concepts
- Karakoram Winter Barrier
- The historical 24-year period between 1987 and 2011 during which all international winter attempts on Pakistan’s five eight-thousanders failed.

Ascent Route & Topography

Southwest Ridge (Normal Route)
The Southwest Ridge is the standard and historically celebrated route on Gasherbrum II (8,035m). Starting from the South Gasherbrum Glacier, climbers navigate the heavily crevassed lower icefall into the Gasherbrum Cwm before tackling the technical crux of the route: the steep mixed snow and ice crest known as the Banana Ridge. Above Camp III, the route traverses expansive snow basins into the Death Zone, making a final push up a delicate diagonal couloir to the summit. First climbed in 1956 by an Austrian team, and completed in rapid alpine style in 1982 by Reinhold Messner, Nazir Sabir, and Sher Khan.
Target Objective Peak
Gasherbrum II
Gasherbrum II, standing at 8,035 meters (26,362 ft), is the thirteenth-highest mountain on Earth and the third-highest peak of the Gasherbrum massif in the Karakoram. Located at the head of the Baltoro Glacier on the Pakistan-China frontier, it features a classic pyramidal profile with challenging ice couloirs. First summited in 1956 by an Austrian team, it was famously climbed in pure alpine style in 1982 by Reinhold Messner, Nazir Sabir, and Sher Khan.
Featured Expedition Climbers

Denis Urubko
Born on July 29, 1973, in Nevinnomyssk, Soviet Union, Denis Urubko relocated to Almaty, Kazakhstan, where he joined the Central Sports Club of the Kazakh Army under legendary coach Ervand Ilyinsky. Urubko rapidly established himself as an elite high-altitude powerhouse, completing the Snow Leopard award by scaling all five 7,000-metre peaks of the former Soviet Union in an astonishing 42 days during the summer of 1999. In May 2009, he became the fifteenth person in history, and the eighth without supplemental oxygen, to summit all fourteen 8,000-metre peaks. Urubko is revered worldwide for his commitment to alpine style and new routes. In 2005, he established a new route on the Southwest Face of Broad Peak with Serguey Samoilov, followed by a new direct route on the Southeast Face of Cho Oyu in 2009, earning two Piolets d'Or. His partnership with Simone Moro yielded the historic first winter ascents of Makalu (2009) and Gasherbrum II (2011). In January 2018, while participating in the Polish winter K2 expedition, Urubko volunteered alongside Adam Bielecki to execute a desperate night rescue on Nanga Parbat, sprinting 1,200 vertical metres up the Kinshofer Route in pitch darkness to save French climber Élisabeth Revol.

Simone Moro
Born on October 27, 1967, in Bergamo, Italy, Simone Moro began rock climbing in the Bergamasque Alps at age thirteen. After qualifying as an instructor and mountain guide, he turned his focus to the Greater Ranges, pioneering lightweight alpine tactics on extreme Himalayan faces. In an era when most major high-altitude triumphs took place in pre-monsoon summer, Moro became the defining force behind the revival of winter eight-thousander expeditions. On January 14, 2005, Moro and Polish partner Piotr Morawski achieved the historic first winter ascent of Shishapangma (8,027m). He followed this triumph on February 9, 2009, by teaming with Denis Urubko to claim the first winter ascent of Makalu (8,485m), enduring temperatures lower than -40°C. In February 2011, Moro, Urubko, and Cory Richards completed the first winter ascent of Gasherbrum II (8,035m), surviving a catastrophic avalanche during their descent. On February 26, 2016, Moro etched his fourth winter summit into history by reaching the top of Nanga Parbat (8,126m) with Alex Txikon and Muhammad Ali Sadpara. In addition to his winter summits, Moro is an accomplished commercial helicopter pilot who has performed numerous record-breaking high-altitude rescues in the Himalayas, including the Fair Play Pierre de Coubertin World Trophy awarded after he aborted his 2001 Lhotse ascent at 8,000 metres to save British climber Tom Moores in darkness.
