A small creek enters from river right just above this last rapid that exists the canyon.  There were photos of this drop being run on the first descent.  In 2013, it was a mandatory portage.  I suspect in recent years a large boulder dropped into the creek creating an unrunnable seive.  Portage on river left or right, but I thought left looked easier.

This is a mandatory portage unless it changes again or the water level is very high.
