Official Expedition Narrative & Archival Record
In late summer 2005, Steve House and Vince Anderson arrived in the Rupal Valley of Pakistan to confront the highest vertical wall on the planet: the 4,100-metre Rupal Face of Nanga Parbat (8,126m). Rejecting heavy siege methods, fixed lines, and supplemental bottled oxygen, they adopted a purist alpine philosophy, carrying tiny packs weighing less than twenty pounds with five days of food and a single lightweight rope. On September 1, they crossed the bergschrund and began climbing the unclimbed Central Pillar. Over the next five days, they executed sustained mixed climbing on vertical granite headwalls and brittle water ice up to Grade VI, M5 X, and WI4. Navigating extreme exposure with zero margin for error, they carved open bivouacs into forty-degree ice slopes each night. On September 6, 2005, despite severe dehydration and exhaustion in the Death Zone, House and Anderson crested the summit trapezoid and stepped onto the 8,126-metre summit of Nanga Parbat. They successfully down-climbed and rappelled the face over the next two days, reaching Base Camp on September 8. Their masterwork was universally acclaimed as a defining pinnacle of twenty-first-century alpinism and awarded the prestigious Piolet d'Or.

Ascent Route & Topography

Central Pillar of the Rupal Face Direct
The Central Pillar of the Rupal Face on Nanga Parbat is the greatest vertical mountain wall on Earth, rising an astounding 4,100 metres from the Rupal Valley floor to the 8,126-metre summit. First attempted over decades, it was conquered in pure, lightweight alpine style between September 1 and 8, 2005, by American alpinists Steve House and Vince Anderson without fixed ropes, high camps, or supplemental oxygen, earning them the prestigious Piolet d'Or.
Target Objective Peak
Nanga Parbat
Nanga Parbat, at 8,126 meters (26,660 ft), is the ninth-highest mountain on Earth and the western anchor of the Himalayas in Pakistan. It boasts the Rupal Face, the highest vertical precipice in the world at 4,600 meters from valley floor to summit. Known for profound climbing history, highlighted by Hermann Buhl's legendary solo summit without supplemental oxygen in 1953.
Featured Expedition Climbers

Steve House
Steve House was born on August 4, 1970, in La Grande, Oregon. Introduced to mountaineering in the Pacific Northwest, House underwent a formative transformation while living as an exchange student in Slovenia in 1988, where he was mentored by the fierce, purist school of Slovenian alpinists. Rejecting heavy siege-style expedition tactics, House dedicated himself to pure alpine style: climbing without fixed ropes, without intermediate high-altitude camps, without high-altitude porters, and without supplemental bottled oxygen. Over the 1990s and early 2000s, House established an astonishing resume of lightweight first ascents in the Alaska Range and Canadian Rockies. Highlights included new direct routes on Mount Bradley, Mount Hunter, and the legendary Slovak Direct on the South Face of Denali, which House, Mark Twight, and Scott Backes climbed continuously in sixty hours in 2000. In 2004, House made an audacious solo ascent of K7 (6,934m) in the Karakoram's Charakusa Valley, a masterwork that garnered international acclaim. In September 2005, House and longtime climbing partner Vince Anderson achieved what is widely regarded as one of the greatest alpine-style ascents in mountaineering history: the direct first ascent of the 4,100-metre Central Pillar of the Rupal Face on Nanga Parbat (8,126m). Climbing over eight continuous days carrying minimalist twenty-pound packs, they navigated vertical granite and brittle mixed runnels to reach the summit, winning the 2005 Piolet d'Or. An eloquent writer and philosopher, House authored 'Beyond the Mountain' and co-founded Uphill Athlete, profoundly shaping the training and ethical standards of modern global mountaineering.

Vince Anderson
Vince Anderson was born on April 15, 1970, in the United States. Drawn to rock climbing and backcountry skiing in the Rocky Mountains and Pacific Northwest, Anderson became one of the premier American mountain guides, attaining full UIAGM/IFMGA international certification. Renowned among peers for his ice-climbing virtuosity, quiet focus, and bulletproof route judgment, Anderson forged a legendary partnership with Steve House, based on shared convictions about fair-means alpine style. In September 2005, Anderson and House journeyed to the remote Rupal Valley in Pakistan to tackle the largest vertical precipice on Earth: the 4,100-metre Rupal Face of Nanga Parbat (8,126m). Rejecting siege tactics, fixed ropes, and bottled oxygen, they launched an alpine-style sprint straight up the Central Pillar. Over eight days of intense climbing, Anderson led critical mixed cruxes through sheer granite bands and crumbling ice flutings. Reaching the summit on September 6, 2005, they completed one of the most revered ascents in alpine history, earning the 2005 Piolet d'Or. Throughout his subsequent career, Anderson continued to open technical alpine routes across Alaska, the Canadian Rockies, the Karakoram, and the Alps. A dedicated mentor and educator, he has served as a senior instructor for the American Mountain Guides Association (AMGA) and co-coach at Uphill Athlete, training hundreds of professional guides and aspiring alpinists. Vince Anderson remains celebrated as a consummate professional whose technical excellence helped elevate modern alpine style to its highest expression.
