Description

This is the approximate start of a half mile of continuous class 4 to 4+ moves, creating the most difficult section of the reach.

This hard rapid ".... links class IV+ moves with only small moves.  A swim would be worse here than any other spot on the run.  In my mind it is the crux of the run.  Plus the rapids ends in a hole that swam one in our group, almost swam another.  and swam one in Darin's first group.  It is a huge hole that feeds into a cave.  our swimmer was in the cave for maybe 1 minute before flushing out, same with our almost swimmer who held her breath for that ~minute upside down in her boat."   Daniel Brasuell 2011.
