Wow...you seem to be alittle defensive. No reason to be as your ski areas seem like great places to ski/ride.
Corbets Couloir is not really a trail, it's gravity then survival. It's dificulty rises and falls with the snowpack. A few years ago a snowmobiler did it...now that's crazy.
The Grand Teton was first skied in 1967, since then snowboarders and teleskiers have conquered it. They do not ski it as a continuous line, that would be impossible, they do rope down over a few sections. Teleskiers can ski anything a alpine skier can do.
I too have never heard of Denton...my bad. That's what so great about all these forums. I love learning about new places.
Hope the Farmers Almanac is right and all of us get a bunch of snow this season for some great skiing and riding. If any of you guys are coming up to New England to ski check in with us at AlpineZone and we would love to share our info or answer any questions you might have.
Cheers
