Entering the High Tibetan Plateau
In September 2019, after brief rest and family reunions in Kathmandu, Nirmal Purja initiated Phase Three: the final three peaks—Cho Oyu, Manaslu, and Shishapangma. Crossing the border into the Tibet Autonomous Region of China, the expedition established Base Camp on the northern side of Cho Oyu (8,188m), the ‘Turquoise Goddess’.
While often characterized as the most accessible eight-thousander, Cho Oyu in autumn presents fierce gale-force winds sweeping off the arid Tibetan plateau, sub-zero temperatures, and vast, energy-sapping snowfields above 7,500 meters.
A Lightning Alpine Strike
Purja had zero interest in protracted acclimatization. Accompanied by Mingma David Sherpa and Gesman Tamang, he launched an alpine-style push from the lower camps directly through the yellow rock band. Moving through sustained 50 km/h winds, the team ascended the wide glaciated Northwest Ridge with machine-like rhythm.
On September 23, 2019, Nirmal Purja stood on the broad, flat summit plateau of Cho Oyu, looking southward toward the distant pyramid of Everest. Peak number twelve was secured.
Turning Toward Nepal
Within minutes of confirming their summit with base camp radio, the team began their descent. They immediately packed their expedition vehicles, crossed the border back into Nepal, and chartered a helicopter for the immediate assault on Manaslu.
