Official Expedition Narrative & Archival Record

In late August 1936, twenty-four-year-old Dartmouth student Jack Durrance teamed up with veteran American Alpine Club climber Kenneth A. Henderson to attempt the most intimidating unclimbed line in the Teton Range: the sheer, shadowed North Ridge of the Grand Teton. Unlike earlier American mountaineers who relied almost exclusively on natural runners or bodily balance, Durrance had spent his youth training in the Bavarian Alps and arrived armed with forged European steel pitons, specialized carabiners, and double-rope technique. Bivouacking high above the icefall of the Teton Glacier at the foot of Mount Owen, Durrance and Henderson launched up the vertical north-facing buttress in icy dawn conditions on August 29. Durrance took the lead on the technical crux pitches, driving pitons into wafer-thin hairline cracks in the vertical gneiss where no human handholds existed. Conquering steep, icy chimneys, sheer slabs, and towering corner systems exposed to the three-thousand-foot abyss of the north face, Durrance solved pitch after pitch of sustained fifth-class climbing. After eleven hours of intense physical and mental exertion, the pair pulled over the north rim onto the sunlit 4,199-metre summit boulder. The 1936 ascent of the North Ridge was immediately hailed by the American Alpine Club as the most difficult technical rock climb completed in the United States to date, firmly establishing the modern era of pitoncraft and extreme wall climbing in North America.

What technical equipment did Jack Durrance introduce on the North Ridge in 1936?

Durrance introduced forged European steel pitons, steel carabiners, and double-rope climbing systems learned during his youth in the Bavarian Alps.

Where did Durrance and Henderson bivouac before climbing the North Ridge?

They bivouacked in the snow beneath Mount Owen above the crevasses of the Teton Glacier at the base of the towering north face.

What were the primary hazards encountered on the North Ridge in 1936?

Hazards included perpetual sub-zero shadow, verglas on the rock, loose flakes, steep overhanging corners, and a 3,000-foot drop into the glacier cirque.

How long did the first ascent of the North Ridge take?

Durrance and Henderson climbed for eleven grueling hours of continuous technical fifth-class pitches before reaching the summit at 4:00 PM.

Who was Jack Durrance's climbing partner on the 1936 North Ridge first ascent?

His partner was Kenneth A. Henderson, a seasoned American Alpine Club climber and author of early climbing guidebooks.

How was the 1936 North Ridge ascent received by the climbing community?

The American Alpine Club recognized it as an epochal breakthrough, marking the beginning of extreme technical wall climbing in the United States.

What route grade is assigned to the North Ridge of Grand Teton today?

The North Ridge is graded Grade IV / YDS 5.8 with ice and mixed sections, remaining a serious and revered North American alpine classic.

Grand Teton

Grand Teton is a world-famous, razor-sharp granite and gneiss peak rising abruptly to an elevation of 4,199 metres in Grand Teton National Park in northwestern Wyoming. As the highest summit in the Teton Range and the second highest peak in Wyoming, it towers more than 7,000 vertical feet above the sagebrush flats of Jackson Hole without intervening foothills. It is celebrated across mountaineering history as the birthplace of modern American technical rock climbing and client-centered mountain guiding.

Born on August 24, 1912, in Florida, Jack Durrance spent several of his formative childhood and teenage years living in Garmisch-Partenkirchen, Germany. Immersed in the Bavarian Alps, he trained with master Austrian and German alpinists, gaining mastery of steel pitons, carabiners, two-rope climbing systems, and body belays decades ahead of typical North American methods. Returning to the United States to attend Dartmouth College in 1935, Durrance brought these modern alpine techniques to the Teton Range, revolutionizing climbing standards between 1935 and 1940. During that golden era, Durrance established an astonishing array of first ascents on the Grand Teton, including the technical West Face in 1936, the North Ridge with Kenneth Henderson in August 1936, and the classic Durrance Ridge on the mountain's east flank. In 1938, he pioneered the historic Durrance Route on Devils Tower in northeastern Wyoming, creating the standard line up the fractured volcanic columns. Selected for the 1939 American Karakoram expedition to K2 under Fritz Wiessner, Durrance carried heavy loads to high camps on the Abruzzi Spur before acute altitude sickness forced his descent. In October 1941, when daredevil parachutist George Hopkins leaped onto the summit of Devils Tower on a bet and found himself hopelessly marooned without ropes as winter blizzards closed in, the National Park Service summoned Durrance. Arriving from Dartmouth, Durrance mobilized an elite climbing team, scaled his sheer namesake route on the monument through freezing sleet, and escorted Hopkins safely down. Durrance later served as an army physician and became a distinguished pulmonary medical researcher in Denver, Colorado. He passed away on November 13, 2003, at the age of ninety-one.
