Lost in the mountains

We get across the suspension bridge fine. And now the trail is covered in snow, the excellent Swiss markings are covered in snow. We spend hours hiking in the snow, often backtracking to find the trail again. At the pass over Col de Riedmatten, we can see the ladder going straight up the mountain; it looks as scary as I imagined it. We can't find the trail to get to it; all the markings are covered in snow. The sun is starting to go down, it is cooling down, we are lost, we still have a very long way to go and I start to panic.
