Granite rapid is another rapid that should be scouted and respected.  At the right levels (between 20K to 40k), the ginormous glass tongue in the center of the river comes in and creates one of the biggest drops on any river in the western US.  This glass tongue and wave curl is known as the green room.  Many boaters choose to skirt the green room on either side.  Below the main tongue, where the whitewater starts, generally contains some fierce lateral waves that have flipped many a boater.

There is a scout trail on river right above the rapid.  Definitely a recommended scout.
