I grew up in Edmonton, a short 3.5 hr drive from Marmot (Marmot Basin). I have skied there no less than 150 days in the last 35 or so years I've been skiing (since 3yr old). In a good snow year (500cm+), there is arguably no better place to ski. Someone else mentioned fresh tracks for a week, it's true, it's not busy, except holidays and usually weekends. The new Crex chair has altered the way the morning flows for me. You used to have to ride 2 chairs to get up to the Triple Face and the Triple is so slow and lines were long, no problem now. You can get a Triple Face face shot run after a storm if you get there early, I mean like first 30 chairs max. If you miss the fresh run there, head to the Eagle Ridge chair for the next chance for fresh, usually open by 9:30ish unless blasting.
If you get the timing right, the glorious Eagle East opens around 10 on a fresh day, after avy bombing of course.
Fresh lines in Eagle East are hard to beat anywhere in the worl, try Easter Alley or Sugar Bowl and see.
Don't get greedy and go too far skiers right, make sure you watch for the signs, and you won't have to walk out as one person said. After a lap in Eagle East I usually watch for the Knob chair to start turning. Most of the knob is high alpine but following the ridge lines you get deep wind deposits along the shrubs and small trees. Knob Hill is a great fall line, as is short skate over to Charlie's bowl and Dupree chutes for 59 degree blown in deepness (2 to 3 times the morning report)on a fresh day.
Hesitantly, I will mention Caribou knoll, I won't tell you where it is, ask a local, if you are not a gaper they will happily tell you.
Enjoy Marmot and follow this order for at least 3 fresh runs guaranteed on even the busiest of pow days.
