I was in this position back in 2009, I chose salt lake city and bailed from california. 40 mins away from downtown you have 7 resorts 4 of those resorts get 500" of snow each season - so plenty of pow days. the other 3 get 350" and have killer parks. one hour away you have 2 more which also get 400-500" of snow. 14 resorts total, killer backcountry with easy access. 4 hours from jackson. seemed like a no brainer to me.
i wasn't ready to go all out and seclude myself in interior bc somewhere, but if i could i would.
IMO, in the US, SLC is the only one that meets your criteria... and then some.
Due to the rising cost of ammo, do not expect a warning shot! Sorry for the inconvenience.
