Grizzly

The rapid starts off as a long moderate class 3 - 4 lead in, then suddenly drops away.    At low flows the ugly undercut boulders at the base of the main drop encourage a portage.   At higher flows it cleans up but can form a huge ugly hole or holes.    There can be a crash and bash sneak route to the right, which feeds back into the main flow just below the main ugly drop.

Cacreeks calls this Kodiak, and others might have different names.   Grizzly is pretty good though as this is the ugliest of the drops in this immediate vicinity.
