Hi Confused,
One great tip I once got was to start out at midnight, Reason being that when your're going up, at least the snow is frozen and you will be walking on top, thus not postholeing as much....which is what kills me!
Mind you, you require headlamps, which aren't bad, but if you've never been there before and kinda know the trail, it is difficult.
I also find it difficult in the spring due to the amount of run off and the creeks can be swollen and difficult to cross.
I'm sure you know, there is a ton of snow this year in that area, so take snowshoes mostly for the decent, or simply slide down but watch out for the bolders!!!
It's a tough test, you can't train for atitude so please realize when you've gone far enough.
Best of luck,
Lance
