Description
This is the biggest rapid in the easy half of the run. A wide horizon line makes it hard to decide where to enter. Scout river left. In the middle of the rapid, rocks clutter the middle and right side. A steep and powerful but clean chute remains on the left. Deal with the hydraulics then decide where to exit. At 1200 cfs the exit (pictured) was particularly congested with ledges and rocks. At higher flows they will be impressive holes.
