Beta for the "gnar" at the canyons
The best terrain I have found at the canyons is off 9990. Follow the liftline most of the way down or take the bootpack through the gate (5-10 minute hike). From the gate, drop to the saddle and make a hard traverse to just below the group of pines. There are several 10-30 drops with decent landings. Be mindful that this is where someone was buried 2 seasons ago. You can also go north after the gate toward square top. There are some good size drops (after another hike) off the south ridgeline into the bowl to the south of square top.
You can find some sketchy terrain mingled with trees off the north side of peak 5 chair, but most of it has thin cover and no clean runouts.
For what you are looking for, you have to go OB. If not, you will get frustrated with super tight tree lines, lifts that go nowhere, and weird cross fall-line runs. However, with a little work, you can have fun all season at the canyons. And you get to ride the cabriolet!
