Description

This is a very long complicated rapid with a number of distinct levels.   At low flows both rafts and kayaks have to maneuver their way past numerous rocks and drop offs.  

 

It is a really tricky rapid that tends to wrap rafts or at least get them very stuck. It is characterized by a long, easy entrance and current that drives into some rocks called "the Jacks." At low water, the classic run is down the right side and then entereing a tricky chute down the middle. Most wraps occur when rafts eddy out on the right just above the tricky chute. The eddy is very tough to leave and they end up wrapped above the chute. At higher water(about 3,000 cfs and above), the middle becomes much more exciting with holes and big waves. At these flows, there is a nice cheat line on the far right. The kayaking lines are pretty much the same and there are probably 5 or 6 fun lines for competent, adventurous kayakers.
