Jim Maxwell
Jim Maxwell was an intrepid American mountaineer and pioneer in post-war Andean exploration. On July 31, 1950, as part of the Harvard Andean Mountaineering Club expedition, Maxwell partnered with Dave Harrah to make the historic first ascent of Yerupajá (6,635 m) in Peru. Overcoming razor-thin snow cornices and frostbite, their climb solved the supreme challenge of the Cordillera Huayhuash.

Biographical Record & Archival Chronicle
James Maxwell grew up in the northeastern United States and joined the Harvard Mountaineering Club following World War II, during an era when American climbers were beginning to match European standards on the world's great ranges. Known for his formidable physical stamina, ice-climbing skill, and rock craft honed in the White Mountains and Shawangunks, Maxwell helped organize the ambitious 1950 Harvard Andean Expedition to Peru. The objective was Mount Yerupajá (6,635 m), the towering second-highest peak in Peru, locally feared as El Carnicero (The Butcher) due to its lethal avalanches and knife-edge summit crest. Establishing a series of camps up the glaciated southwest slopes from Laguna Jahuacocha, Maxwell and his collegiate climbing partner Dave Harrah were selected for the final summit assault. On July 31, 1950, Maxwell and Harrah pushed through intense cold, step-kicking up 60-degree firn and delicately traversing monstrous overhanging double cornices suspended over 4,000-foot precipices. At late afternoon, they stood victorious atop Yerupajá's 6,635-metre pinnacle, claiming the first ascent of the greatest unclimbed peak in the Americas. Caught by darkness during the descent, the pair were forced to endure an unplanned open bivouac at 6,500 metres in temperatures plunging far below zero. Despite severe frostbite that later required the amputation of several toes, Maxwell displayed magnificent fortitude in shepherding his frostbitten partner down the mountain to safety. Maxwell's ascent marked the coming-of-age of American high-altitude mountaineering in the Andes and earned him enduring respect in alpine history.

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.
