Description

The most challenging rapid on the run. Look for the horizon line at the end of a long pool. Manuver through the boulders at the start to line up for the center slot that feeds into a wave train. Following the entrance, you will need to negotiate another quarter mile of rocks, waves, and holes that slowly tapers off.
