Screaming S-Turn Rapid
Screaming S-Turn Rapid is named for the move that you'll have to make if you choose the left hand line. From the entrance you'll have to ferry far enough to the left to avoid a pinning rock and a nasty undercut slot. At higher flows the push of the water makes for a small margin of error. By 2800 cfs (Fall Flow), most rafters will opt for the line down the right side.
The right hand route is pretty straightforward. Just be sure to get far enough to the right to avoid the retentitive ledge hole.
