SNOTEL is showing about 5 feet of snow at 9000 feet just down the road. Corral Hollow goes up to about 8000 feet. And that would not be any drifts in the trees.
Good trail, has a good camp site above the ski run and some farther west along the ridge. I think I have been through in early June, but I can not remember how the snow pack was that year. You should be able to see when someone goes through on pirate4x4.com or ih8mud.com, or ask through guys on those sites.
