The Sierra City run.
Wild Plum canyon is one of the uppermost regions within the North Fork Yuba River.
The only creeking above this point is 40 degree gradient on mixture of sharp granite substrates that few salmon can make it past.
We dubb this the Sierra City run.
Sikbird note: This run can be notched up considerably by adding the Love Falls section above the Pacific Crest Trail bridge.
Seasonal rain and snow events frequently bump this run up quickly.
This run offers clear and cold water, beautiful and challenging rapids in steep gradient with real consequences for the uninitiated.
