Description

Coming out of the pool below Kil'n Ledge, the flow spills down brief rubble-filled gradient then heads toward a rock wall on river-left.

Large tree trunks had blocked this area for a few years. They have been cut so this should be passable next time there are boatable flows, but (once again) you really need to scout this area before putting on, to be sure there is no impassable wood in this stretch.

To avoid being stuffed into the undercut/overhanging wall, point bow to the right or even angled upstream and paddle to stay center-river!
