Le Grand Armet, Alpine summit in Taillefer Massif, Isère, France.

Le Grand Armet is a summit of the Taillefer Massif in the French Alps, in the Isère department, reaching 2,792 m. Its crest forms a jagged, multi-peaked ridge of bare rock, with steep gullies and ribs running down from the top; snow patches linger in the gullies and on ledges of the darker lower slopes, and bare trees stand below the shadowed flank.

The sources record no founding event, construction or historical episode for Le Grand Armet; it is documented as a 2,792 m summit of the Taillefer Massif in the Dauphiné Alps, in the Isère department. Its north-facing slope carries the Grand Glacier, described as one of the few true glaciers of the massif despite its modest size.

The name Armet refers to the mountain's shape, likened to a helmet. The summit stands at 2,792 metres in the Taillefer Massif, within the Isère department, and its north-facing slope holds the Grand Glacier, one of the few true glaciers of the massif.

Le Grand Armet reaches 2,792 m in the Taillefer Massif, in the Isère department. The sources describe no marked trail to the summit, so approach and route must be planned from the valley, and the bare rock, steep gullies and snow patches seen on the upper slopes call for alpine equipment and timing around snow conditions.

The Grand Glacier lies on the mountain's ubac, the shaded slope away from the sun, and is modest in size yet counts as one of the only true glaciers in the Taillefer Massif. The summit itself reaches 2,792 m in the Isère department.
