From the bottom of Toilet Bowl, follow the flow back to the left side of the river. As the gradient increases, you will approach a small drop with a weird seam. Keep driving left here toward --but not into-- the left wall. The river will start falling off quickly to the right, going under what appears to be the worst undercut you've ever laid eyes on. Keep driving left, point back slightly right, and pull on a right boof through the hole. The trick here is to keep enough downstream angle that you don't piton the rock, but not so much that you slide into the hole sideways.
This rapid is a hard one to style, but quite forgiving, all things considered. Many paddlers have royally messed up the line, receiving pitons and scraped knuckles as the standard punishment. A swim here is considered to be highly inconsequential at anything less than high flows.
As the water level rises, the left pothole at the bottom of the drop can start to get some teeth.
