The Golden Standard: Štremfelj and Prezelj on Kangchenjunga South Ridge

By the early 1990s, high-altitude mountaineering was experiencing a deep philosophical identity crisis. Massive national sieges using thousands of meters of fixed ropes, legions of high-altitude porters, and hundreds of oxygen bottles had turned Himalayan climbing into heavy industrial campaigns. Many purists lamented that the true soul of alpinism—self-reliance, lightweight speed, and the vulnerability of human beings facing vast mountain walls on equal terms—was being extinguished in the death zone.

Then, in October 1991, two Slovenian climbers arrived at the foot of Kangchenjunga (8,586m) in eastern Nepal. Thirty-four-year-old Andrej Štremfelj, already an immortal hero for his 1979 first ascent of Everest’s complete West Ridge, joined forces with twenty-six-year-old rising phenomenon Marko Prezelj. Their objective was monumental: the unclimbed, 3,000-meter South Ridge leading to the South Peak of Kangchenjunga (8,476m). Their style would be uncompromising: pure alpine style, carrying all their survival gear in their backpacks, with no supplemental oxygen, no fixed lines, and no safety net.

Into the Vertical Wilderness

Departing from the Yalung Glacier on October 15, 1991, Štremfelj and Prezelj carried forty-pound packs containing only minimal dehydrated food, stove fuel, a tiny two-man bivouac tent, and a single climbing rope. As soon as they stepped onto the lower granite ribs of the South Ridge, there was no retreat. Every pitch required total commitment.

Over the next four days, the climbers worked through technical mixed rock buttresses up to Grade V and 65-degree flutings of hard blue ice. Unlike standard Himalayan routes where climbers retreat to comfortable camps each night, Štremfelj and Prezelj carved tiny bivouac ledges into knife-edge snow crests at 7,200 meters, 7,600 meters, and 7,900 meters. The cold was searing, and their bodies burned immense calories simply maintaining core temperature against sub-zero Himalayan jet stream squalls.

The Death Zone on Natural Lungs

Above 8,000 meters, technical rock climbing on natural lung capacity is an extraordinary test of physical conditioning and willpower. Every move required delicate balance on crumbly granite footholds while fighting the suffocating hypoxia of the death zone. Prezelj, possessing immense youth and ferocious drive, alternated leading pitches with the seasoned, methodical Štremfelj.

On the morning of October 19, 1991, after five continuous days of ascending into the sky, the two men breached the final corniced snow shoulder. Moving together along the razor ridge, Andrej Štremfelj and Marko Prezelj stepped onto the 8,476-meter summit of Kangchenjunga South. Below them stretched the boundless mists of Nepal and Sikkim, with the colossal pyramid of the main summit towering nearby.

The Inaugural Piolet d’Or

After a harrowing two-day descent down the Southwest Face, the climbers returned to Base Camp safe, frostbite-free, and triumphant. In 1992, when the French Groupe de Haute Montagne established the Piolet d’Or—mountaineering’s equivalent of the Academy Award—Štremfelj and Prezelj were unanimously chosen as the inaugural laureates. Their climb stood as an unassailable declaration that the highest peaks on Earth could be climbed in pure alpine style, ushering in the modern era of visionary Himalayan exploration.
