I wonder how much of this is just the fact that main ski resorts started when the 10th came home from WW2.

Those guys ended up founding alot of these resorts. Areas in the backcountry, where the land was super cheap and they managed to get leases for them for pennies.

Over time they became more commercial and less of a personal project. Plus these areas became more valuable because of the skiing and that priced out the locals, the people that actually worked the slopes.

I think this story is way more complex then to point to climate change.
