I was there in February.
The park was pretty pathetic. there was a super-steep urban style setup with a downbox, downrail, and downrail with those lame little kinks at the end, then there was an uprail, a super burl flat down, and some wooden jib that looked lame. There was also a box on top of a quarterpipe. There was a single stepdown, with 2 takeoffs that felt way kicky. Then there was a halfpipe that wasn't completed and roped off.
The small park had 3 small jumps (10 feetish...) with trannys like quarterpipes. there was a cool up-down rail, and 2 small 12 foot boxes with trannys like quarterpipes. There was a wooden wallride, and some sort of rythm section with trannys likequarter pipes. then there was a 2 inch, 6 foot long flat rail with no takeoff that put you off a 5 foot drop into the trees.
That was all they had.
HOWEVER.... if you go to big sky for the park, I will find you and punch you in the eyeball. Big Sky is a dope mountain... I don't think I would really ride park at all if i lived there
