The Inside Line: Mick Fowler & Paul Ramsden on Mount Siguniang

Deep in the Qionglai Mountains of Sichuan, China, Mount Siguniang (6,250m)—known as the ‘Four Sisters Mountain’—rises in a sensational fortress of granite needles and towering rock faces. While its lower summits had seen occasional ascents, the colossal Northwest Face of the highest summit remained one of Asia’s most feared mountaineering enigmas: a sheer 1,500-metre wall of smooth, compact granite cut by thin, discontinuous runnels of alpine ice.

In April 2002, British amateur alpinists Mick Fowler and Paul Ramsden arrived in the Changping Valley. Known for balancing full-time professional careers with daring expeditions to remote alpine big walls, the pair committed to a pure alpine-style approach: no pre-placed fixed ropes, no bolts, no supplementary oxygen, and no support teams on the face.

Entering The Inside Line

On April 20, 2002, Fowler and Ramsden crossed the bergschrund and stepped directly into the icy maw of the face. Their objective was a hidden system of ice runnels that threaded between smooth granite slabs, a line they christened ‘The Inside Line’.

The technical climbing was ferocious from the first day. Pitch after pitch demanded sustained water-ice climbing up to grade WI6, with ice axes scratching into veneer-thin verglas that barely supported their crampon front-points. Mixed sections reached Scottish VI and M6, where the climbers were forced to torque picks into blind granite cracks while hanging above thousands of feet of sheer void.

Seven Days in the Spindrift

Because the Northwest Face is largely vertical or overhanging, suitable bivouac ledges were virtually non-existent. For six consecutive nights, Fowler and Ramsden slept on narrow snow hummocks chopped out of sixty-degree ice slopes or hung from gear anchors, battered by constant spindrift avalanches that cascaded down the wall.

On April 26, 2002, low on rations and enduring severe cold, the pair surmounted the final precarious snow cornice and emerged onto the 6,250-metre summit of Mount Siguniang. Exhausted but triumphant, they navigated a complex and treacherous descent down the Southeast Ridge and Southwest Gully, returning to base camp on April 28 after an eight-day ordeal.

The ascent was hailed internationally as an uncompromising masterpiece of modern alpine style, earning Fowler and Ramsden the prestigious 2002 Piolet d’Or and setting a benchmark for exploratory climbing in the mountains of Western China.
