AlpinePDMixedNormal route

The only relatively easy way up, rarely climbed: from the Refuge du Pelvoux (about 2,700 m) over the rock barriers and moraine to the Bosse de Sialouze, up the Glacier de Sialouze towards the Col W du Pelvoux, then a long, almost level traverse across the loose south-east face and a 100–150 m snow couloir to the summit. Graded PD, but on snow and very poor rock.

From Ailefroide walk up the Celse Nière valley and the path to the Refuge du Pelvoux (about 2,700 m). From the hut climb the first rock band to the north (recce it the evening before; steps of about II), then a path to the crest of the left-bank moraine of the Glacier de l'Homme, a level traverse exposed to serac fall from the Glacier du Clot de l'Homme at its start, and snow or scree slopes to the flat area north of the Bosse de Sialouze (3,229 m). Rope up and follow the Glacier de Sialouze north-north-west, keeping the crevassed zone on the left, towards the Col W du Pelvoux (3,573 m), about 3 hours from the hut to the Pelvoux cols. Below the col, leave the glacier by a short gully (an abseil anchor is in place for the descent) onto the south-east face of the Pic Sans Nom below its east shoulder, and traverse almost horizontally, rising slightly, across the whole face to the foot of the snow couloir that falls from the summit on the south side. Climb the couloir for 100–150 m to the top. The rock on the face is rotten and stones fall frequently. Descend the same way, about 2½–3 hours from the summit to the hut: go down the summit couloir, traverse the whole face towards the Col du Pelvoux, and do not try to drop to the Glacier de Sialouze too early. Camptocamp notes that the route is very rarely used and is not necessarily the most practical or safest; many parties prefer harder but sounder lines.

Overview

The Pic Sans Nom (3,913 m), the 'nameless peak', is a huge granite and gneiss block between Mont Pelvoux and the Ailefroide in the Écrins. Its north side above the Glacier Noir is a great wall of hard classic and modern climbs, while the PD normal route on the south-east side is loose, rarely used and serious.

The Pic Sans Nom sits in the middle of the long, steep ridge that runs south-west from Mont Pelvoux to the Ailefroide, with the Pic du Coup de Sabre (3,699 m) as a western subsidiary summit. Its north face, rising above the Glacier Noir, is one of the major walls of the Écrins, with lines such as the north-west couloir, the Chapoutot-Lemoine and the George-Russenberger, and modern rock routes like Aurore Nucléaire.

The south side, bounded by the Glacier du Coup de Sabre and the Glacier de Sialouze, gives the only relatively easy access. The normal route from the Refuge du Pelvoux crosses the Glacier de Sialouze and then traverses the south-east face on snow and bad rock. It is graded PD, but Camptocamp counts the Pic Sans Nom among the most difficult summits of the massif: every route has a long and delicate descent, and the normal route itself is rarely climbed.

The mountain lies in the core zone of the Écrins National Park.

Climbing Notes

Treat the Pic Sans Nom as a serious mountain even by its normal route: you need glacier skills, fast movement on loose rock and snow, and the judgement to find a line on a face with little traffic and frequent stonefall. Stay at the Refuge du Pelvoux (booking required; staffed late May to late August), recce the rock barriers above the hut the evening before, and leave early, as the slopes towards the Bosse de Sialouze face east and soften quickly. Early summer, with snow on the glacier and in the summit couloir, is usually the best time. A guide is strongly recommended for anyone without experience of loose Écrins terrain.

History

The first ascent was made on 10 July 1877 by John Brise Colgrove and Richard Pendlebury with the guides Gabriel and Joseph Spechtenhauser, by the south-east side. The second ascent, in 1879, was by Antoine Giraud-Lézin, Paul Guillemin, Émile Pic and André Salvador de Quatrefages, also by the south-east side. W. A. B. Coolidge, Frederick Gardiner and the Almers followed in 1880. The east ridge and south-east face were first climbed on 20 June 1907 by Edward Lisle Strutt with Aloïs and Joseph Pollinger.
