Visibility deteriorated significantly.
I had heard a helicopter flying back and forth above me for a while, but I’d not been able to see it. However, finally I had started to get glimpses of it through the murk. It was apparently ferrying building materials to some workmen that were maintaining the avalanche fences very high up on the mountainside.
At one point, when it was a little clearer than this, I raised my arms to take a photo of the helicopter, as is customary these days when peering at the little screen on the back of a compact camera, and the helicopter fellows must have spotted me and thought I was waving for assistance. They flew over and circled me a couple of times before satisfying themselves that I was in fact in no need of assistance at all.
Note to self - take care when trying to take photographs of nearby helicopters in geographically challenging locations.
