Of course there are more consequential lines out west. Of course there are more intimidating looking lines out west. You can also get away with a lot due to the snow quality out west. Skiing Paradise with frozen bumps is hard. Skiing Main Chute, with average snow at Alta is not.
Either east or west, the difficulty is modified by snow conditions, and western ski areas are not immune to poor snow conditions (hardpack, ice, obstacles due to low snowpack). For example, it’s not uncommon to find hardpack in the W/B alpine after freeze thaw conditions. Also, it is not uncommon for a tame line one year to be a horrifying nightmare another because of changes to wind deposition or lack of snow.
Elsewhere in the west, I have been “fortunate” enough to ski slide or die hard pack off of Lone Peak, refrozen crud at JH, sheets of ice at Telluride, top-to-bottom “firm” conditions at Kicking Horse, frozen man-eating bumps at Taos (and I could go on).
I’ve personally found the Cottonwoods to be an exception and not representative of an entire half of a continent.
The difference with something like Paradise, which people ski all the time in poor conditions, is that it’s certainly challenging, maybe not fun, and possibly increases the likelihood of injury. When conditions are poor at W/B, which is more common than people would like to admit, no one skis the high consequence lines because doing so could result in death. Hell, many of those lines are only skied in the absolute best of conditions—and even then there is no room for error.
