Deep in the Baltoro Glacier
Trekking for days across the moraines of the Baltoro Glacier, Nirmal Purja reached Concordia and the Gasherbrum Base Camp on July 8, 2019. Standing at 8,080 meters, Gasherbrum I—historically known as Hidden Peak—is tucked behind a fortress of surrounding ridges, protected by the chaotic, serac-laden Gasherbrum Icefall.
With summer temperatures creating dangerous wet-snow avalanches in the lower icefall, Purja adopted nighttime operational hours. Moving between midnight and sunrise, Purja, Mingma David Sherpa, and Geljen Sherpa navigated gaping crevasses to establish Camp 2 on the high plateau.
The Japanese Couloir
The defining section of Gasherbrum I is the Japanese Couloir—a sustained 50-degree ice chute ascending directly to the upper ridge. Purja led the climbing through hard blue ice and loose scree, driving ice screws and establishing fixed ropes under severe physical strain.
On the morning of July 15, 2019, Purja and his Nepali squad breached the upper cornice and stood on the summit of Hidden Peak. It was his eighth 8,000-meter peak of the year, achieved just twelve days after Nanga Parbat.
Eyes on Gasherbrum II
Descending directly to the high camp, Purja did not celebrate. Across the glaciated col stood the symmetrical pyramid of Gasherbrum II. Project Possible’s tactical playbook demanded an immediate follow-up strike.

Gasherbrum I
Gasherbrum I, at 8,068 meters (26,470 ft), is the eleventh-highest mountain in the world. Named 'Hidden Peak' by explorer William Martin Conway due to its concealment behind surrounding Karakoram giants, it stands on the border between Pakistan and China. The peak was first climbed in 1958 by an American team led by Nick Clinch, and in 1992 Nazir Sabir summited it with Rajab Shah and Mehrban Shah, marking his fourth Pakistani eight-thousander.
