Afaik, it wasn't foggy when he was taking photos and fell off. It was at the top though. They rescued him by chopper and choppers wouldn't go in fog. I think the cornice broke off like 20 ft back from the lip. But I'm not totally clear on that.
There was another incident of someone up near the top of the chair or whatever structure is there. I think they went under a rope to take photos or get a view.They fell off and were killed I believe.
Fog in totally unknown terrain is difficult. If it's questionable exposure you might have to stay in place.
What I discovered in Chamonix was mainly stop trying to see. You can't, so trying just sets yourself up to go crazy and or be very timid. I figured this out asking wtf? when I was getting passed by other skiers in fog and the people were not good skiers.
Do regular turns, focus on the turn. How much are you going up, edge angle, skidding/carving, accelerating etc. that gives a sense of the pitch. Plus it's something to occupy the mind.
The "feel with your feet" thing to me is just another form of trying to see. Plus it's too late. You're going to feel it anyway, you can't control the surface. Focus more on what the feet are doing to the skis.
I used to do the uphill pole drag to feel the slope. But it's a bad habit in my regular skiing so I eliminated that. I might tap though just to get some feedback or again have something to occupy a mind that wants to freak out with no visual cues.
Breathe.
There prob will come a monent of freak out. Then just stop and try to regroup. No sense fighting it.
In terms of the stop trying to see, my analogy is if the lights go off and you need to cross a room. Now you could freak and imagine Freddy Kruger coming out of the closet. But nothing has changed in the seconds it got dark. So the mind is just making stuff up. In the fog it wants to do the same.
