Coldsmoke beat me to a reply.
I've been to Great Divide on several occasions. First time on my first 2002 tour around WA/ID/MT which whetted my appetite for organizing my on trips, skiing all over the USA and of course MT.
I can't really disagree with much of what Coldsmoke has said although my recollection is of reasonable intermediate groomers over on the Wild West lift. I'd also add that for me it seemed that it didn't need much snow to operate as the mountain seemed to be mostly meadow from what I recall on a warm spring day a few years back, that compared to much of Discovery which requires significant snow to ski on the backside.
Coldsmoke is also correct that Great Divide had a banner year. When I arrived at Discovery my buddy Jim was telling me that our large Helena contingent had not been around much this year as conditions at Disco v GD meant staying closer to home was the best option.
Discovery's skier visits were certainly down this year. My buddy works in the Sunshine Station and has the job of counting the lift tickets that are clipped in exchange for free beer/pop and normally they get ~10% of skier visits doing that each season. I think he said they were about 2000 tickets behind this season compared to last so 20000 skier visits less for the hill perhaps.
Discovery having a poor season by most accounts
Discovery had a very poor Nov-mid Feb for certain. From that point on they had a pretty good season which suited me perfectly and is the reason I visit in March. Coverage on the front side through closing day was as good or better than most years and the backside skied extremely well right through closing. Coverage at the bottom of Granite did well to see the season out though.
I was talking on the phone to my buddy Jim last week and we were just saying that in my 6 weeks out there we had very few freeze/thaw cycles which is very unusual for late March/April at Discovery. I skied 1 day on cement on Limelight just because that's where I ski, and maybe a couple days where I skied only on aspects in the direct sunshine. Normally I would factor in many more days of spring conditions but for the most part it was winter conditions with great coverage.
