Mountain Overview

K2, at 8,611 meters (28,251 ft), is the second-highest mountain on Earth and widely regarded as the most technically demanding and lethal 8,000-meter peak. Located in the heart of the Karakoram on the border between Pakistan and China, K2 is characterized by sheer relief, severe weather anomalies, and persistent objective hazards including the notorious Bottleneck couloir.

Geographical Setting

Baltoro Muztagh subrange of the Karakoram, situated at the head of the Godwin-Austen Glacier in northern Gilgit-Baltistan.

Historic First Ascent

Date: July 31, 1954
Ascent Team: Achille Compagnoni and Lino Lacedelli (Italian Karakoram Expedition led by Ardito Desio)

Abruzzi Spur (Southeast Ridge)

The most celebrated and attempted route on K2, tracing the Southeast Ridge from Base Camp at 5,000m to the summit pyramid. It demands mastery of sustained mixed climbing through House's Chimney (6,600m), the sheer granite slabs of the Black Pyramid (7,200m), and the treacherous traverse beneath the colossal hanging serac of the Bottleneck (8,200m).
