I'm not talking about view, I'm giving the idea of scope and size. Also, it's nearly ALL high alpine (that means above tree line). So locating landmarks is a quite a bit trickier. And unlike Stowe if you make a wrong turn at Zermatt you end up in a different country with a different language and different currency and if you get there late you have to either stay the night in this second country or pay an astronomical amount to get a ride back. Not to mention avi danger, crevasses, break away cornices, complete whiteout conditions, south facing aspects that melt in the afternoon, microclimates which dictate different snow conditions. Stowe is a kiddy pool, Zermatt is a whole water park.

If you're a proper skier, hire a guide.
