That late in Feb you should have about 6 hours of daylight
yep. 6-7 hours... about the same we have in October, so really you also have some dusk time too. However, I'll warn you that February is part of the coldest part of the year. It's a shame you wouldnt have a couple days to go down to Alyeska.. it'll be warmer there with more daylight. But hey - doesnt hurt to try... bring your gear and by then I'll know my way around. I'll look into Birch Hill for you - I keep thinking they have night boarding so maybe you could hit up two places.
If you come next year, I'll for sure have a snow machine. haha
