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.

“Chogolisa was lost in a sea of gray vapor, the wind tearing across the ridge with blinding force. One step too close to the edge, and the silent white ledge vanished into the abyss.”
Defined Alpine Terminology & Concepts
- Bride Peak
- The historical name given to Chogolisa by Martin Conway in 1892, honoring its sweeping snow mantle resembling a bridal gown flowing from the summit crest.
- Cornice Fracture
- A sudden structural collapse where wind-compacted snow shelves overhanging mountain precipices break under pressure, posing an extreme objective hazard on knife-edge alpine ridges.

Documented Climbing Routes (1)
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.

Frequently Asked Questions: Chogolisa
What is Chogolisa and why is it called Bride Peak?
Chogolisa (7,665m) is a prominent glaciated mountain located in the Karakoram range of Gilgit-Baltistan, Pakistan. Explorer Sir William Martin Conway named it Bride Peak in 1892 because its broad, elegant, snow-draped profile resembles a bridal veil cascading across the sky.
What historic altitude record was set on Chogolisa in 1909?
In 1909, Prince Luigi Amedeo, Duke of the Abruzzi, reached an elevation of 7,498 meters (24,600 feet) on Chogolisa’s Southeast Ridge without supplemental oxygen, establishing a world altitude record that stood unbroken for 13 years until 1922 on Mount Everest.
What happened to Hermann Buhl on Chogolisa in 1957?
On June 27, 1957, Austrian climbing pioneer Hermann Buhl and Kurt Diemberger made an alpine-style push reaching ~7,300 meters on Chogolisa. Forced to retreat by a sudden blinding blizzard, a massive snow cornice collapsed beneath Buhl’s feet, plunging him 900 meters down the North Face. His body was never recovered.
Who completed the first ascent of Chogolisa?
Fred Pressl and Adolf Bräunlich completed the first confirmed ascent of Chogolisa on August 4, 1958, via the Southeast Ridge as members of an Austrian expedition led by Eduard Koblmüller.
