Michel-Auguste Croz
Michel-Auguste Croz was the supreme Chamonix mountain guide of the Alpine Golden Age — bold, fast, technically masterful, and universally beloved by the British climbers he led. Croz pioneered first ascents of the Barre des Écrins in 1864, the Grandes Jorasses in 1865, and led the summit rope on the Matterhorn on July 14, 1865, only to be torn to his death on the descent in the most famous mountaineering tragedy of all time.

Biographical Record & Archival Chronicle
Born in Le Tour in the Chamonix valley on April 22, 1830, Michel-Auguste Croz was raised among the great glacier torrents and granite aiguilles that define the Mont Blanc massif. He became a professional mountain guide at an early age, quickly distinguishing himself for an uncanny speed and sure-footedness on Alpine terrain that seasoned British climbers found breathtaking. By the early 1860s, Edward Whymper — whose Matterhorn obsession would define the decade — specifically sought out Croz above all other guides, writing admiringly that Croz was the finest guide he had ever climbed with. Together they pioneered first ascents of extraordinary difficulty. In August 1864, Whymper, Croz, and a small team completed the first ascent of the Barre des Écrins (4,102 m), the highest peak of the Dauphiné Alps, a serious mixed route demanding navigation of steep glaciers and exposed ridges. In June 1865, Croz stood on the summit of the Grandes Jorasses above Chamonix — one of the most impressive north-facing walls in the entire Alps — completing another major first ascent. In the fateful summer of 1865, Croz joined Whymper's team for the Matterhorn. On July 14, Croz led the final ridge approach with characteristic boldness, racing ahead of the party and arriving at the summit alongside Whymper in a sprint. He sat on the summit to eat and rest before organizing the descent rope order. On the descent near a patch of snow above the couloirs that plunge into the Matterhorn Glacier, the inexperienced Douglas Hadow lost his footing. Croz, who had just stepped forward to assist Hadow, was pulled violently off his stance. Four men — Croz, Hudson, Hadow, and Lord Douglas — plunged 1,200 metres and fell to their deaths on the glacier below. Croz was thirty-five years old. His death devastated the British climbing community and effectively marked the end of the Golden Age of Alpinism.

Associated Summits (2)
Matterhorn
The Matterhorn (Monte Cervino), at 4,478 meters (14,692 ft), is one of the most recognizable and dramatic pyramidal peaks in the world. Straddling the border between Zermatt, Switzerland, and Breuil-Cervinia, Italy, its four triangular faces match the cardinal points of the compass. Its historic first ascent by Edward Whymper on July 14, 1865, and the tragic fall of four teammates on the descent marked the end of the Golden Age of Alpinism.
Grandes Jorasses
The Grandes Jorasses, crowning at Pointe Walker at 4,208 meters (13,806 ft), is one of the most celebrated mountain massifs in the European Alps, rising along the Franco-Italian border in the Mont Blanc massif. Its legendary 1,200-meter sheer North Face is revered as one of the Six Great North Faces of the Alps. First climbed directly up the central Walker Spur by Riccardo Cassin in 1938, it witnessed a historic modern milestone in March 2015 when British solo climber Tom Ballard completed his winter solo hexalogy of the Alps.
Pioneered & Associated Routes (3)
Walker Spur (North Face)
The Walker Spur on the North Face of the Grandes Jorasses is one of the supreme classic alpine mixed routes in the world. Ascending 1,200 metres directly to Pointe Walker (4,208m), it features sustained technical climbing across granite slabs, icy dihedrals, and exposed arêtes graded ED1, with difficulties up to UIAA VI / 5.10a. Conquered in August 1938 by Riccardo Cassin, Gino Esposito, and Ugo Tizzoni, it achieved modern acclaim when Tom Ballard made an astonishing solo winter ascent in March 2015.
Hörnli Ridge (Normal Route)
The Hörnli Ridge (Hörnligrat) is the northeast ridge of the Matterhorn and the standard normal route from Zermatt. Starting from the Hörnli Hut (3,260m), the route follows the sharp, crumbling crystalline schist ridge, traversing steep rock steps, the Solvay emergency refuge (4,003m), and the steep upper Moseley Slabs. Fixed ropes assist climbers over the steep summit headwall (the Shoulder) before reaching the knife-edge Swiss summit crest at 4,478 meters. First climbed on July 14, 1865, by Edward Whymper's party.
Matterhorn Lion Ridge (Cresta del Leone)
The Matterhorn Lion Ridge (Cresta del Leone / Italian Normal Route) is the historic Italian line to the Matterhorn summit, ascending from the Rifugio Theodul and Breuil-Cervinia on the Italian south-west face via the Col du Lion, the Tête du Lion, and the Great Tower. Pioneered by Jean-Antoine Carrel on July 17, 1865 — three days after Whymper's Hörnli ascent — the Lion Ridge remains the longer, more exposed, and more technically demanding of the two standard Matterhorn routes, graded AD+/D with sustained UIAA IV passages and dramatic 3,000-metre drops into the Valtournenche.
