Elbow room is considered the crux of the upper canyon stretch. This is a short but swift boulder section with a large rectangular rock splitting the current in two paths. The rapid must be run river right (at standard levels) where there is just enough room to squeeze your boat through. Beware, the passage is off-camber and you may find yourself losing some skin as you pass through. Elbow pads recommended. A couple quick moves immediately after will get you around the bend where you're met with 2 more small funnel drops. A fun, fast 1/4 mile.
