1936 Schneider-Awerzger Siula Grande Historic First Ascent Expedition
On July 28, 1936, Austrian alpine legends Erwin Schneider and Arnold Awerzger accomplished the historic first ascent of Siula Grande (6,344 m) in the Cordillera Huayhuash. Navigating intricate crevasse fields and knife-edge corniced ridges, Schneider and Awerzger achieved the first high-altitude triumph in this formidable and unexplored mountain range.

Official Expedition Narrative & Archival Record
Following his groundbreaking 1932 successes in the Cordillera Blanca, Austrian photogrammetrist and mountaineer Erwin Schneider directed his exploratory focus toward the uncharted Cordillera Huayhuash in the austral winter of 1936. Accompanied by experienced alpine companion Arnold Awerzger, the small Austrian Alpine Club party conducted pioneering photogrammetric mapping of the region's colossal peaks. Operating from a primitive base camp on the western shores of Laguna Sarapococha, Schneider scouted the formidable ramparts of Siula Grande (6,344 m). On July 27, Schneider and Awerzger pushed past the broken lower glacier to establish a bivouac below the northern saddle. At dawn on July 28, 1936, the pair mounted a relentless assault along the corniced North Ridge, overcoming vertical flutings of soft tropical snow, towering seracs, and gaping bergschrunds. After hours of exacting step-cutting and delicate ridge balancing, Schneider and Awerzger stood on the virgin summit of Siula Grande. Their ascent represented the first recorded summit climb in the Cordillera Huayhuash and laid the cartographic foundation for modern exploration in the range.

Frequently Asked Questions: 1936 Schneider-Awerzger Siula Grande Historic First Ascent Expedition
Who made the first ascent of Siula Grande in 1936?
Austrian topographer and mountaineer Erwin Schneider and Austrian climber Arnold Awerzger achieved the historic first ascent of Siula Grande (6,344 m) on July 28, 1936.
What route did Erwin Schneider and Arnold Awerzger climb on Siula Grande?
They climbed the North Ridge from Laguna Sarapococha, negotiating broken glaciers, steep firn couloirs, and dangerous overhanging snow cornices along the northern crest.
Why was the 1936 Schneider-Awerzger expedition historically significant?
It was the first successful summit climb in the Cordillera Huayhuash and enabled Schneider to conduct pioneering terrestrial photogrammetry that produced the first accurate map of the range in 1939.
What scientific contributions resulted from the 1936 expedition?
Erwin Schneider utilized terrestrial phototheodolites to calculate triangulated summits, glaciological profiles, and base contours across the Cordillera Huayhuash for the German-Austrian Alpine Club.
Ascent Route & Topography
Siula Grande West Face
The West Face of Siula Grande is one of the most celebrated and formidable alpine routes in South America. Rising 1,000 metres above the glacier of Laguna Sarapococha, the line tackles 80-degree water-ice flutings, fragile powder mushrooms, and vertical mixed headwalls. First climbed in June 1985 by British alpinists Joe Simpson and Simon Yates in lightweight alpine style, it became the crucible for one of mountaineering's most legendary survival epics.
Target Objective Peak
Siula Grande
Siula Grande is a majestic 6,344-metre mountain in the Cordillera Huayhuash of the Peruvian Andes, renowned for its sheer western precipice, knife-edge corniced ridges, and one of mountaineering's greatest survival sagas. First climbed in July 1936 by Austrian alpinists Erwin Schneider and Arnold Awerzger via the North Ridge, the peak earned worldwide fame from Joe Simpson and Simon Yates' harrowing 1985 first ascent of the West Face, chronicled in Touching the Void.
Featured Expedition Climber
Erwin Schneider
Born in Sankt Joachimsthal on April 13, 1906, Erwin Schneider became one of the most prolific high-altitude mountaineers of the twentieth century. In 1928, as a member of the German-Soviet Alay-Pamir Expedition, Schneider summited Lenin Peak (7,134 m) alongside Karl Wien and Eugen Allwein. In 1930, during the International Himalaya Expedition to Kangchenjunga, Schneider summited Jongsong Peak (7,462 m), setting an undisputed world altitude summit record that stood for years. Schneider's greatest lasting legacy lies in high-altitude photogrammetry and mountain cartography. Between 1955 and 1963, Schneider led the Austrian Alpine Club mapping expeditions that created the legendary 'Schneider Map of the Khumbu Himal and Mount Everest', widely regarded by geographers and mountaineers as a masterpiece of cartographic precision.
