Brush Creek into the Kern
Brush Creek flows into the North Fork Kern on river left just above the rocky drop called, oddly enough, Brush Creek rapid. It is a short run with very high gradient, and no portages in the steep first mile. After that come a few 20' falls that are a blast to run. It's a must do if you are in the area. Amazingly, a strong class IV boater can handle the run with no problem.
Chris Shackleton, who maintains Dreamflows, created this webpage showing over half a dozen great photos of kayakers on Brush Creek.
