Mont Dolent

4,032 m

French for 'painful' or 'sore mountain' — the etymology is contested. The standard reading takes the modern French dolent at face value ('sore'); a competing scholarly view sees it as a corruption of an older Patois oronym, possibly related to dolomite or to a local word for 'border' (appropriate, since the peak is the tripoint of France, Italy and Switzerland).

History

The 'painful mountain' — a small pyramidal summit standing at the meeting point of France, Italy and Switzerland (the only true tripoint on the international watershed of the Alps). Climbed on 7 July 1864 by Whymper's party on the same Dauphiné–Alps tour that took in Barre des Écrins ten days earlier; it was the last summit of that highly productive trip. The name dolent has been variously read as 'sore' (French dolent) or as a corruption of an old Aosta dialect word for 'peak'; both etymologies are still argued in local sources.

Editor's note

Figures approximated from CAI guidebook. Bivouac is small (~12 places) and unguarded; bring everything.

N ridge from Refuge d'Argentière (technical alternative)

D · difficile

Vertical / summit day1,300 m gain · 8h

A serious snow-and-mixed ridge from the French side. Sustained 50–55° snow with mixed sections (III); committing, with serac hazard on the upper face. Much harder and less popular than the Italian normal route.
