FOR ME, MOUNTAIN PICKING is usually a 3-3-3 game: 3,000+ acres skiable terrain, 3,000ft vertical, 300+ inches snow/year, give or take.
Truly epic ski trips, on the other hand, I measure by a different count: number of resorts. No matter how close together two areas are, each has its own vibe, its own terrain, its own locals, its own stashes.
Here are some of the best thoroughfares on the continent that weave big mountains into big trips.
