Dave Harrah
Dave Harrah was an intrepid American mountaineer, scholar, and philosophy professor celebrated for one of the greatest triumphs of twentieth-century American alpinism. On July 31, 1950, Harrah partnered with Jim Maxwell to make the historic first ascent of Yerupajá (6,635 m) in Peru. Despite suffering severe frostbite during an emergency bivouac, Harrah exemplified extraordinary courage and brotherhood.

Biographical Record & Archival Chronicle
Born in 1926, David Harrah graduated from Harvard University, where he distinguished himself as both an exceptional intellect and an accomplished rock climber with the Harvard Mountaineering Club. In the summer of 1950, Harrah served as a core climbing member of the Harvard Andean Expedition targeting Mount Yerupajá (6,635 m), the second highest mountain in Peru and the undisputed monarch of the Cordillera Huayhuash. Known locally as El Carnicero, the mountain had repulsed prior European scouting parties. Harrah demonstrated remarkable icecraft, pioneering the technical passages through the lower icefall and kicking thousands of steps up the steep firn slopes of the southwest wall. Paired with Jim Maxwell for the final push, Harrah led portions of the knife-edge South Ridge, gingerly straddling overhanging snow mushrooms suspended above dizzying abysses on either side. Reaching the summit late in the day on July 31, 1950, the pair celebrated a historic milestone for American mountaineering. During the perilous descent in fading light, a snow bridge collapsed, and the climbers were forced into an emergency open bivouac at 6,500 metres in brutal freezing winds. The night of extreme exposure caused catastrophic frostbite to Harrah's feet, ultimately requiring the surgical amputation of all his toes. Despite this life-altering injury, Harrah maintained a deep love for mountaineering literature and pursued an illustrious academic career, serving for decades as Professor of Philosophy at the University of California, Riverside, where he was a leading scholar of formal logic, semantics, and game theory.

Yerupajá
Yerupajá is the second-highest peak in Peru and the undisputed monarch of the Cordillera Huayhuash, soaring to 6,635 metres. Celebrated for its razor-sharp summit cornices, vertical ice walls, and ominous local moniker El Carnicero (The Butcher), it was first climbed in July 1950 by Jim Maxwell and Dave Harrah of the Harvard Andean Mountaineering Club. In 1968, Chris Jones and Paul Dix completed the first ascent of its fearsome 1,200-metre West Face.

Yerupajá West Face and South Ridge
The historic first ascent route of Yerupajá ascends the glaciated western cirque and tackles the ferocious, cornice-hung South Ridge to reach Peru's second-highest summit at 6,635 metres. Pioneered on July 31, 1950, by Harvard mountaineers Jim Maxwell and Dave Harrah, the route demands mastery of steep 60-degree firn, rotten limestone crags, and nerve-testing overhanging double snow cornices suspended over two-mile drops.

1950 Harvard Andean Yerupajá Historic First Ascent Expedition
On July 31, 1950, American climbers Jim Maxwell and Dave Harrah of the Harvard Andean Mountaineering Club achieved the historic first ascent of Yerupajá (6,635 m), the second-highest peak in Peru. Enduring extreme cornice balancing and an unplanned open bivouac at 6,500 metres that caused severe frostbite, their ascent was hailed as a milestone of post-war North American alpinism.
1968 Jones-Dix Yerupajá West Face Historic Direct Ascent
On July 27, 1968, British climber Chris Jones and American alpinist Paul Dix, supported by Dean Caldwell and Leif Patterson, completed the historic first ascent of the terrifying 1,200-metre West Face of Yerupajá (6,635 m). Braving relentless spindrift avalanches, vertical ice flutings, and hanging bivouacs, they unlocked the premier big-wall ice face of the Andes.
