Just got back from whistler today.
The double blacks I Skiied:
Whistler:
Cockalorum
The Cirque
Horseshoe Chutes
Harmony Cliff-walls (lol - off to the right as you go up the chair)
Blackcomb:
Spanky's Ladder
Blow Hole
Pakalolo
Outer Limits
No doubt there are some drop in's back at spankys ladder that are scary. I did a few 20-40 foot straight chutes at 50+ deg slopes between rock sidewalls where you COULD NOT turn even slightly. Some with rocks in the middle you had to drop from at speed etc etc. Basically if you slip.....splat.
Also, coverage on the Couloir Extreme/Jersey Cream bowl was sketch. Probably the scariest full run on the entire mountain. Incredibly steep and conditions at the top can be horrible. We are talking icy moguls mixed with sharp rocks. You can't air the rocks because you land in moguls....the moguls are incredibly steep and icy and if you slip you are luck to walk away from it.
I saw some guy fall on his first turn coming down through a more difficult entrance on the right side of Couloir Extreme and he rolled half way down the run - probably 600ft - hitting multiple huge rock walls on the way down. I would be amazed if that fool walked away.
You can get into a lot of trouble very quickly up there if you don't know what you are doing and where you are going. I honestly don't think the steepness of a run is what makes it scary. It's the rocks.
Always the rocks.
