Hey EpicSki dudes. I like your site! You definitely list most of the best extreme terrain, and lots of ball busters and butt tightening lines.
First, regarding your rating of Ski Areas with EX terrain, if in Summit County you're going to list the Lake Chutes at Breckenridge, as this makes sense, then you'd also have to put A-basin's upper east wall on your map. I dare you to drop into the Second Notch from the summit and not rate it more severe than any Lake Chute, Breckenridge run.
Enough on that, as it takes me to this interesting topic. Yes, alpine ski categories are flat out confusing across the board.
For example, you can go to many areas and see double black and not realize you're heading over to 50 -60 degree chutes. Okay, yes, you'd have to ignore a plethora of other warning signs, but I see big caution and hazard signs to sleeper terrain, too.
Of course, looking down a true in-bounds extreme line from the top shoud give every gumby a clew, but it doesn't. While filming at the Breckenridge Lake Chutes over the last few weeks I filmed no less than 8 falls that exceeded 400-500ft. Fortunately, most of those marvelous double black experts survived falling from the cornice to the valley floor. Again I have to agree with your blog topic, "Alpine Ski Categories are Confusing, for sure." Why not go to triple black diamonds for 50-60 degree terrain between rock bands that run for more than 700ft? Well, ski areas have their little motives, including being scared to admit this to the general public, so it's not likely to happen.
For that reason, I propose referencing the R and D Wildsnow Rating by Dobson be applied to true inbound EX terrain, so there is at least some shread of comparison to off piste terrain hazards. If we do a bit of that type of communicating, fewer double black experts that spend 2 days skiing a year will drop into a bad inbound spot, all the while knowing that yes ski patrol does dynamite in-bound ex slopes for safety, and will hall a sorry ass out of places like Corbits if an accident happens. Good topic, yes evolution in gear should be followed by an evolution in communicating an extreme ride.
Cheers, good blog!
