Southeast Ridge (Standard Route)
The Southeast Ridge of Chogolisa (7,665m) ascends from the upper Chogolisa Glacier, scaling steep ice couloirs to gain the elegant, wind-sculpted snow arête leading toward the summit. First explored in 1909 by the Duke of the Abruzzi to 7,498 meters, attempted in alpine style in 1957 by Hermann Buhl and Kurt Diemberger, and first summited on August 4, 1958, by Fred Pressl and Adolf Bräunlich.

Tactical & Camp Notes
While free of extreme vertical rock cruxes, the Southeast Ridge presents treacherous navigational hazards in bad weather. Wind-sculpted snow cornices overhang the sheer North Face, making precise ridge adherence vital during storms.
Identified Objective Hazards
- •Treacherous overhanging snow cornices that can collapse without warning during whiteouts
- •Sudden, violent Karakoram storms bringing blizzard conditions and rapid temperature plunges
- •Crevasse danger along the upper Chogolisa Glacier approach
- •High-altitude pulmonary and cerebral risks in the thin air above 7,000 meters
Historical Context
In 1909, Prince Luigi Amedeo reached 7,498m here, setting a world altitude record. In June 1957, Hermann Buhl fell to his death when a cornice gave way during an alpine-style retreat with Kurt Diemberger.

Mountain Ascended
Chogolisa
Chogolisa, standing at 7,665 meters (25,148 ft) in the Karakoram range of Pakistan, is renowned as Bride Peak for its broad, graceful snow-draped profile. Located south of Concordia and the Baltoro Glacier, it features two prominent summits connected by a sweeping knife-edge snow ridge. In 1909, the Duke of the Abruzzi set a world altitude record on its slopes, and in 1957, it became the site of alpine pioneer Hermann Buhl's fatal cornice fall.
