Mostly pleasant (40's to 60's at night). I camped up their 3 times back in June & July (watched fireworks) of 2010. I might have been lucky, but the wind was mild unlike last night when I was on top and the winds were strong and cold. I didn't camp last night. Just hiked around and came down at midnight. I also camped on the ridge at top of the switch backs to the west of the Ski Hut (and a little south down the ridge) in early July 2010. In April 2009, I camped at the Ski Hut and had a freak night of heavy wind, branches falling, and temps in the high teens. I was glad I brought my four season tent and proably will not camp under trees again.
