Description

Follow the Les Rognons descent onto the Argentiere Glacier, then skin as you would initially for the Col d'Argentiere line.

Head up very gently until the first glacial basin on the left after the obvious Argentiere Hut, visible on the moraine above.

The Col d'Argentiere line now carries on up the flat glacier, but you head up and left for the tour described here.

The first part is possibly the steepest but barely reaches 30 degrees.

It then mellows off before a slightly steeper section again as you go up and left under the Aiguille d'Argentiere, with its beautiful red granite pinnacles and the Y Couloir above you.

Further easy ground above leads slowly to a final short steepening to the col itself.

Descend the same way, then back onto Les Rognons, joining all the other tracks from the Grands Montets and down to the pistes.
