"Dislocation"

'Dislocation' Rock is tucked against the right side of the river and has a noticeable undercut feature.   A nasty hole is just above the rock and should be avoided between 3.75 (~1,000 cfs) and 5.5 (~2,500 cfs) feet on the Ferndale Gauge.   There are a series of glassy surfing waves with good eddy access just behind the rock up to 6 feet (~3,000 cfs) on the USGS Ferndale Gauge.
