What resort has the most vertical serviced by a single high-speed detachable or tram.

l would think one of the European resorts like Chamonix that have a Telecabine from the bottom to the top. In Nth America it used to be Jackson Hole, but the tram is not there at the moment.

If l had to guess, it would be Whistler/Blackcomb. l know it has the most vertical feet of ski-able terrain in North America, if not the world. l do not know if it is all serviced by one lift, though.

But, it literally has a mile of vertical terrain, with over 5,000 ft. No other resort that l know of, even where l live in Colorado, comes close to 5,000. A few top out in the low 4,000 range, and high 3,000. Vail, Snowmass, Beaver Creek, Aspen.
