William Howard, Narrative of a Journey to the Summit of Mont Blanc
“ We had been compelled a little before, by the precipices of the Aiguille du Midi, which presented themselves like a wall before us, to change our direction, and instead of proceeding parallel to the glacier, to strike off suddenly towards it. We had now a close view of some of the obstacles which bar the approach to Mont Blanc; the glacier of Boissons, on which we were about to enter, seemed to me absolutely impassable. The only relief to the white snow and ice before us, was an occasional rock, thrusting its sharp point above their surface, and too steep to permit the snow to lodge on it. ”
