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.

Tactical & Camp Notes
Extremely exposed to westerly jet stream gales with no possibility of rapid descent once committed to the upper crest. Demands supreme physical conditioning and rock climbing mastery at extreme altitude.
Identified Objective Hazards
- •Devastating westerly jet stream gales along the razor crest that can blow climbers off the ridge
- •Technical mixed rock and ice climbing at altitudes exceeding 8,200 meters
- •Dangerous Lho La ice cliff approach hazards
- •Extreme exposure with several thousand meters of vertical drop on both the Tibetan and Nepalese flanks
Historical Context
First climbed on May 13, 1979, by Andrej Štremfelj and Nejc Zaplotnik, followed on May 15 by Stane Belak, Marjan Manfreda, and Ang Phu Sherpa (who tragically perished during descent). It remains one of the greatest technical achievements in the history of Everest exploration.

Mountain Ascended
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.
