I edited my TR from 08' in this thread, post #17:
When would be the best period if the powder is the priority? (Is it mid Feb to mid March like everywhere else?)
We were there in mid-March. My understanding is that this is about when the real season begins to kick in for this operation. Prior to that it is mostly guide school & recon going on. After that it is lots of film crews. The season runs till the end of April. The group I went with go this same week every year to avoid competition with the film crews & the influx of regular clients. Heli-skiing in AK is always a crapshoot as far as weather & down days go. I think the chances of drier snow are better in March than April. If I ever get the chance to go again, I would stay for 2 weeks minimum.
Which is the best operator?
I couldn't really say. We skied with Alaska heli-skiing. They were the first of 2 operators. Seaba I think, is the other one. I believe they offer a cat-skiing option for down days & are more ski package oriented. AK heli is very bare bones, but incredible.
What kind of skiing can you get? Is it only high alpine 50 degree spines, or is there some tree skiing and other stuff as well?
Not much tree skiing in my short experience. Not all 50 degree spines either, but you better bring your A-game. The terrain you ski will depend on the group you are skiing with and the conditions.
Is there any lift carried resort within reasonable driving distance to combine with?
Eaglecrest ski area in Juneau is the only one I know of. You cannot drive from Juneau to Haines. Access is either by ferry or air.
Or do you have any other suggestions instead of Haines?
I have heli-skied a in a few other places on day trips as well as a week at Wiegle's in British Columbia. Top notch operation, accomodations, food etc. Great terrain, weather & snow. Very upscale & more expensive. Much more of a vacation experience than AK. With that said I would jump at the chance to do either again, but Haines was more of what I am looking for.
