1978 Latok I North Ridge Alpine Expedition
In the summer of 1978, American alpinists Jim Donini, Michael Kennedy, George Lowe, and Jeff Lowe mounted a legendary alpine-style attempt on the 2,500-metre North Ridge of Latok I (7,145m), reaching within 150 metres of the summit before surviving a harrowing six-day blizzard retreat.

Official Expedition Narrative & Archival Record
In June 1978, four of America's finest alpinists—Jim Donini, Michael Kennedy, George Lowe, and Jeff Lowe—approached the unclimbed North Ridge of Latok I (7,145m) above the Choktoi Glacier in the central Karakoram. Eschewing siege tactics, high-altitude porters, and supplemental oxygen, the four-man team launched a pure alpine-style assault up 2,500 vertical metres of knife-edge granite crests, steep icefields, and difficult mixed headwalls. Climbing continuously for three weeks, they pioneered over eighty technical pitches in severe conditions, overcoming difficulties up to 5.9 and A2 on vertical rock and WI5 on steep ice. By late July, having endured twenty-one days on the ridge, the team had reached 7,000 metres—just 150 vertical metres below the summit cornices. There, disaster intervened: Jeff Lowe was stricken by acute high-altitude pulmonary edema and hypothermia, while a catastrophic multi-day Karakoram storm enveloped the mountain with hurricane-force winds and torrential snowfall. Recognizing that continuing to the summit would mean certain death for Lowe, the team abandoned their summit bid and initiated an epic retreat. Over six grueling days of near-zero visibility and constant spindrift avalanches, they executed eighty-five rappels down iced rock faces, carrying and lowering their incapacitated comrade, before finally staggering safely onto the glacier. The 1978 Latok I attempt is universally celebrated in mountaineering history as one of the finest, most courageous alpine efforts ever undertaken.

Archival Primary Source Quotations
“Getting Jeff down alive was our greatest triumph. The summit would have been nice, but bringing our brother home was everything.”
Defined Alpine Terminology & Concepts
- High-Altitude Pulmonary Edema (HAPE)
- Fluid accumulation in the lungs caused by extreme altitude, resulting in shortness of breath, cyanosis, and fatal asphyxiation if untreated.
- Snow Bollard
- A teardrop-shaped trench carved into hard snow around which a climbing rope is looped to serve as a temporary rappel anchor.
Frequently Asked Questions: 1978 Latok I North Ridge Alpine Expedition
Who were the climbers on the legendary 1978 Latok I North Ridge expedition?
American alpinists Jim Donini, Michael Kennedy, George Lowe, and Jeff Lowe.
What style did the four climbers employ on the 2,500-metre North Ridge?
Pure alpine style, carrying all supplies on their backs without fixed ropes or supplementary oxygen.
How high did the team climb before retreating?
They reached 7,000 metres, just 150 vertical metres below the 7,145-metre summit.
Why did the team abandon their summit bid at 7,000 metres?
Jeff Lowe was incapacitated by high-altitude pulmonary edema and hypothermia during a savage storm.
How long did the descent take and how many rappels were made?
The descent took six grueling days through spindrift avalanches, requiring 85 separate rappels.
How many total days did the team spend on the mountain?
Twenty-six consecutive days above the Choktoi Glacier in extreme conditions.
Why is the 1978 Latok I attempt called alpinism's greatest near-miss?
Because of the unparalleled technical commitment and the heroic selflessness demonstrated in saving Jeff Lowe.
How long did the North Ridge of Latok I remain unclimbed after 1978?
Forty years, until Aleš Česen, Luka Stražar, and Tom Livingstone reached the summit via the ridge and face in 2018.
Ascent Route & Topography

Latok I North Ridge
The North Ridge of Latok I (7,145m) is widely regarded as one of the most formidable and iconic alpine objectives in the Karakoram. Rising 2,500 vertical metres from the Choktoi Glacier along an unbroken, knife-edge spine of vertical granite, seracs, and steep mixed ice, it resisted dozens of the world's finest alpine attempts for forty years.
Target Objective Peak
Latok I
Latok I is a formidable 7,145-metre granite spire situated in the Panmah Muztagh subrange of the Karakoram in Gilgit-Baltistan, Pakistan. Rising steeply above the Choktoi and Baintha Lukpar glaciers, Latok I is internationally celebrated for its sheer 2,500-metre North Ridge, widely regarded as one of the most demanding alpine challenges on Earth.
