This is not a rapid it is a hazard there is a big logjam down river from Coal Creek.    The main channel heads into the log jam so be sure to go right. The gps coordinates are for  channel you should take (right) to bypass the log jam.  Update June 2017 there is much more wood that has drifted into the channel that  heads into the log jam if you take the right hand channel at the waypoint  you will easily bypass the log jam.  The GPS coordinate is for the correct channel, go right.  If you miss the first right hand channel there is a second one.
