Rope teams spread out over the Valley in the shadow of Mont Blanc du Tacul. I often found myself unable to judge the scale of the landscape without seeing people in it. Even with tiny dark figures against the mass of white, it was easy to misjudge distance or size. You’d set out towards a feature and by the time you reached it, the rock/ice wall/crevasse would turn out to be several times bigger than you’d first thought. When trudging long distances I’d often try to keep my eyes cast down at the floor for as long as possible, only to look up and feel like I hadn’t moved at all.
