Official Expedition Narrative & Archival Record
In spring 1979, the Yugoslav Mount Everest Expedition led by Tone Škarja confronted the most formidable unresolved objective on the world's highest peak: the complete West Ridge Direct. While the American 1963 expedition had climbed a portion of the ridge before diverting into the Hornbein Couloir, no team had ever climbed the entire, razor-sharp western crest from the Lho La pass directly to the summit. Over weeks of brutal winds and bitter cold, the team fixed ropes up the sheer rock steps of the ridge. On May 13, 1979, Nejc Zaplotnik and Andrej Štremfelj pushed out from Camp V at 8,120 metres into the Death Zone. At 8,300 metres, they encountered the terrifying crux of the Yellow Band—a vertical wall of crumbly limestone and rotten snow graded V+. Clinging to micro-holds with freezing fingers in howling wind, Zaplotnik managed to lead the pitch without falling. Continuing along the knife-edge cornices, they stepped onto the 8,848-metre summit of Mount Everest at 1:45 PM. Caught by nightfall during their descent down the Hornbein Couloir, they survived an emergency open bivouac at 8,400 metres in minus forty degrees without shelter, descending safely the following morning. Their ascent stands as one of the absolute masterpieces of Himalayan mountaineering history.

Ascent Route & Topography

Mount Everest Complete West Ridge (Yugoslav Direct)
The Complete West Ridge of Mount Everest is one of the most formidable and sustained technical routes on the mountain. Pioneered in spring 1979 by an elite Yugoslav expedition led by Tone Škarja, the route tackles the integral knife-edge crest directly from the Lho La col (6,026m) all the way to the 8,848.86m summit. Unlike the 1963 American West Ridge route which diverted into the Hornbein Couloir from the North Face, the Yugoslav line stayed strictly along the razor-edge crest of the West Ridge, surmounting technical rock buttresses up to Grade V+ at extreme altitude before traversing around the Yellow Band. On May 13, 1979, Andrej Štremfelj and Nejc Zaplotnik achieved the first ascent of the complete ridge, followed two days later by Stane Belak, Marjan Manfreda, and Ang Phu Sherpa in one of the greatest feats in Himalayan history.
Target Objective Peak
Mount Everest
Mount Everest is the highest mountain above sea level on Earth, standing at an official elevation of 8,848.86 meters (29,031.7 ft). Straddling the international frontier between Nepal and China, it is known locally as Sagarmatha in Nepali ('Goddess of the Sky') and Chomolungma in Tibetan ('Mother Goddess of the World'). The peak rises into the extreme upper troposphere, where oxygen levels drop to barely one-third of sea-level pressure. Climbers face hurricane-force jet stream winds, severe frostbite conditions, shifting ice crevasses in the Khumbu Icefall, and the dangerous Death Zone above 8,000 meters.
Featured Expedition Climbers

Andrej Štremfelj
Andrej Štremfelj was born on December 17, 1956, in Kranj, Slovenia. Beginning his climbing journey in the Julian Alps and Kamnik-Savinja Alps at fifteen, he rapidly became one of the leading figures in the golden generation of Slovenian alpinism. In 1977, at just twenty years of age, he made his Himalayan breakthrough on Gasherbrum I (8,080m) alongside Nejc Zaplotnik, opening a new route on the southwest face. Two years later, in spring 1979, Štremfelj was selected for the landmark Yugoslav Mount Everest Expedition led by Tone Škarja. The team tackled the formidable, unbroken West Ridge of Mount Everest directly from the Lho La col (6,026m). Operating at the absolute outer limit of physical endurance, Štremfelj and Zaplotnik surmounted steep, crumbly limestone bands (Grade V+) and navigated the knife-edge crest in devastating westerly gales. On May 13, 1979, they reached the 8,848-meter summit, completing the first ascent of the complete West Ridge—a line that has never been repeated in its entirety and is celebrated as one of the hardest routes ever climbed on Everest. In October 1991, Štremfelj teamed up with young climbing partner Marko Prezelj to make a pure alpine-style first ascent of the 3,000-meter South Ridge of Kangchenjunga (8,476m South Peak) without supplemental bottled oxygen. The climb was hailed as a benchmark for fair-means Himalayan exploration and earned the duo the inaugural Piolet d'Or in 1992. In 1990, Štremfelj summited Everest again with his wife Marija Štremfelj, becoming the first married couple to stand atop Everest together. In 2018, the international mountaineering community honored him with the Piolet d'Or Carrière (Lifetime Achievement Award).

Nejc Zaplotnik
Jernej 'Nejc' Zaplotnik was born on April 16, 1952, in Kranj, Slovenia (then part of Yugoslavia). From a young age, Zaplotnik displayed a poetic soul paired with extraordinary physical stamina and fearless technical skill in the Julian Alps. He quickly rose to become the emotional heart and leading visionary of the golden generation of Slovenian and Yugoslav alpinism, which startled the global mountaineering community throughout the 1970s and 1980s with their uncompromising boldness on the world's most daunting big walls. Zaplotnik made international headlines in October 1975 as part of the Yugoslav expedition to the colossal South Face of Makalu (8,485m). Climbing in extreme conditions, Zaplotnik and his partner reached the summit via a new direct line on the southern wall, marking Yugoslavia's first conquest of an eight-thousander. Two years later, in July 1977, Zaplotnik teamed up with Andrej Štremfelj to forge a bold new route on the Southwest Ridge of Gasherbrum I (8,080m) in the Karakoram, completing their second eight-thousander without supplemental oxygen. Zaplotnik's defining crowning achievement arrived on May 13, 1979, during the historic Yugoslav Mount Everest Expedition led by Tone Škarja. Tackling the complete, unbroken West Ridge Direct from the Lho La—widely regarded as one of the hardest routes on Mount Everest—Zaplotnik and Štremfelj surmounted the terrifying technical crux of the Yellow Band (V+) at 8,300 metres amidst hurricane-force winds to reach the summit at 8,848 metres. During their desperate descent into the Hornbein Couloir, they survived a harrowing open bivouac at 8,400 metres in minus forty-degree temperatures. In 1981, Zaplotnik published 'Pot' ('The Path'), an existential and deeply moving philosophical autobiography that became a sacred text for mountain lovers across Southeastern Europe. Tragically, on April 24, 1983, while leading an expedition on Manaslu (8,163m), Zaplotnik was swept away by a colossal serac ice avalanche below Camp I and killed at the age of thirty-one. His grave rests at the foot of Manaslu, eternally facing the Himalayan skies he so passionately revered.
