Arguably most difficult at 4-5'. Above 5', things begin to wash out, though there are some BIG holes and waves.
(AKA "Rocky Road" - which some older rafting guidemaps call this rapid, assuming a line straight down the center.) Most hard boaters call this rapid "Maze" as they prefer to find their own route through the boulders on river left. The "Maze" line is more fun than difficult.
