Looks amazing up there! Hoping to get on some Canadian ice this winter myself. Could a Subaru Outback make the approaches?
Unless driving conditions are ideal I wouldn't suggest it.
We went in to the Sorcerer last February in far snowier conditions and had no trouble in Subaru Outback. I'm 99% sure we drove the standard "North Ghost" approach, but then had to park a mile or two before where someone in a hi-clearance 4WD car could get to, but the subsequent walk was flat. We used hefty trash bags to keep our feet dry on a couple shallow stream wadings.
Maybe the roads all degraded over the summer, but there are multiple approach roads for the area, so maybe the road the John and his friends drove was different than our road. (The Waiparous Option
sounds more like 5.10 driving...)
Great photos! The top pitch on the Sorcerer was wild.
