I ski there, I'll describe the parks for you...
The miniest of mini parks is at sesame street under the beginner chair. I went there to learn 270, and we go through there on our way from some other parts of the mountain and back through main. It usually consists of, in order:
1 half pipe (really just sloped walls, doesn't get above a 40 degree angle,
1 12 foot long rail, 8 inchers fat
1 box, 8 foot long and 1.5 foot wide
1 box 8 foot long by about 8 inches wide
2 flat rails, about 10 feet long and 4 inchers wide
sometimes 1 3 foot flat to 4 foot down rail.
And all along side there are either small tables (like 3 feet tall and 5 feet long) or rollers
All of these rails are no more than a 10 inches off the snow.
The next step up, the "family fun park" consists of
2 boxes like the two mentioned above,
usually 1 flat rail that's 8 inches fat and about 8 or 10 feet long,
various small tables, like 3-5 feet long,
1 halfpipe with like... 10 foot walls. but it's seriously a full on halfpipe. Hard to ride on full size skis.
Then there is South park, which has small tables, up to about 10 feet, and some intermediate rails, but mostly larger features.
Next there is Forest trail, right to the skier's right of the Main Unbound. There you will find, on any given day:
Intermediate rails... maybe a downrail, maybe a flat rail, maybe a flat box, all about 16 feet long,
3 decent sizeed jumps, anywhere from 15 to 30 feet, depending on the day.
4 small jumps, anywhere from 6 to 14 feet
and usually some sort of smaller feature at the end, like a small wallride, a quarterpipe with a rail at the top, or a small hip/spine.
Main Park and South Park change too much to name everything, but there are all sorts of very large features, step-downs, step-ups, tables, rails, boxes, and every once in a while something new and wierd. This year we had one of those snow box things. There is a Rail Park and Boardercross/Skiercross sort of course on the right of South Park.
