Conquering The Butcher: The 1950 Harvard First Ascent of Yerupajá

In the heart of the Peruvian Andes, rising like a jagged blade of ice above the alpine lakes of the Cordillera Huayhuash, stands Mount Yerupajá. At 6,635 metres (21,768 feet), it is the second-highest mountain in Peru and one of the most terrifying massifs on Earth. Quechua villagers referred to it as El Carnicero—The Butcher—a name born from the thundering avalanches that constantly tore down its fluted walls.

By 1950, Yerupajá stood as the highest unclimbed peak in the Americas. European and South American expeditions had scouted its approaches and retreated, intimidated by its vertical ice headwalls and monstrous, overhanging summit cornices.

The Harvard Mountaineering Club Takes Up the Challenge

In the spring of 1950, a group of bold collegiate mountaineers from the Harvard Mountaineering Club decided to test themselves against the giant. Led by Jim Maxwell and Dave Harrah, and supported by George Bell, Chuck Matthews, Graham Matthews, and Austen Riggs, the young Americans assembled an expedition characterized by exceptional camaraderie and technical daring.

Establishing their Base Camp at the emerald shores of Laguna Jahuacocha at 4,050 metres, the team gazed up at Yerupajá’s staggering 8,000-foot western face. Recognizing that a direct assault was suicidal due to ice avalanches, Maxwell and Harrah mapped an intricate route threading through the glaciated southwest cirque toward the razor-sharp South Ridge.

Over weeks of exhausting effort, the team ferried loads, kicked steps across 50-degree firn ramps, and established Camp 1 at 5,200 metres, followed by a precarious Camp 2 perched on an ice terrace at 6,100 metres beneath the summit ridge.

The Knife-Edge Ridge of El Carnicero

On July 31, 1950, Jim Maxwell and Dave Harrah set off on their final summit bid. The climbing immediately entered terrain of unprecedented extremity. To gain the summit, they were forced to traverse the South Ridge—a knife-edge spine of rotten firn draped in gigantic double cornices that hung out over multi-thousand-foot voids on both sides.

In places, the ridge was so sharp that the climbers had to straddle it like a horse, kicking their feet into empty air on either side. A single cornice collapse would plunge both men into the abyss. Maxwell and Harrah took turns leading, carefully testing each snow mushroom with their ice axes before trusting their weight to it.

At 5:30 p.m., under a deepening purple sky, Maxwell and Harrah crested the final snow dome and stepped onto the virgin summit of Yerupajá at 6,635 metres. They had solved the greatest unclimbed problem in the Western Hemisphere.

The Ordeal of the Sub-Zero Bivouac

Their triumph was instantly shadowed by mortal danger. With sunset fading into bitter Andean darkness, the climbers had to retrace their steps across the corniced ridge. As Harrah crossed a narrow snow bridge, the structure gave way beneath him. Maxwell arrested the fall with a lightning-fast ice-axe belay, but Harrah’s pack slipped into the chasm.

Stranded on a narrow ledge at 6,500 metres in temperatures plunging below minus-twenty degrees, and without sleeping bags or a tent, the two men had no choice but to endure an open bivouac. Throughout the endless night, they beat their hands and stamped their boots against the ice to fend off deadly hypothermia.

By morning, Harrah’s feet were frozen solid like blocks of wood, and Maxwell’s fingers were blackened with frostbite. In an epic display of will, Maxwell belayed Harrah down pitch after pitch of steep ice until their waiting teammates from Camp 2 rushed upward to assist them.

Although Harrah ultimately lost his toes to frostbite, the 1950 Harvard ascent of Yerupajá was celebrated internationally as one of the bravest and most audacious achievements in the history of American mountaineering.
