There was a thread made a little while ago called "Unique Jib/Jump Features" that had some really cool ideas from people. Heres the link to it:
Here are the ones I supplied to it:
This is like a quarterpipe to stall. There is a block of snow behind it in case someone falls, or for butters and tail taps off the logs.
A Quarterpipe extravaganza. Lots of possible lines, but a little advanced for most riders. Still, it would make an excellent feature to hold a comp. in.
Another quarterpipe-stall feature, this time using a chair from a chairlift.
I have no idea. The mushroom is like a box that you can hit from any angle. The middle one is a table with a box as the takeoff. The front one is a multi feature thats like a c-rail under a sort of urban drop. You go off the top and gap the rail or hit the rail and go around. Meh.
I really like lofty rollers and step ups because you get lots of airtime with little risk. The jump here has about 6 inches of lift, but the slope is made so you're always about 2 to 1 foot above it for around 40 or so feet. The box is just a c or a u that goes through the jump, i know its impracticle, but hey.
A wallride on a chairlift pole. Almost every park has a chair going through it, why not just build a little QP for some fun?
Yeah, its like the tree stall in "WAR", but two of them, 7 or 8 foot gap between with a rainbow rail between the two trees, making a mandatory clearance level for anyone trying to air it. I really donít expect to see anything like this just hanging around in a park, but maybe some film crew might eventually do something like this.
Thatís all Iíve got for now. Hope your park building goes well!
