At this level, 60/40 Falls is Class III+, The Slide is Class IV, and S-turn is Class IV+.
One of the largest and most fun Class IV drops in the state. Extreme caution should be used on this drop at higher water levels. At 800 cfs and above, the bottom hole becomes terminal at far river left, and a swim there could prove fatal.
Typical line: Start river right in the pool above the drop. There is a wide wave-hole at the top of the slide, so try to punch that hole. Failing to do so will typewriter you left and put you in a less-than-desirable position for the big slide. Once you punch the top hole, stay to the right side of the big slide, stay straight, and you will have plenty of speed to blast through the bottom hole and into the pool below.
At low flows (50-200 cfs), this rapid becomes more of a low-consequence water slide (Class III+.) At high levels (> 800 cfs), it becomes more of a Class V (but with numerous sneaks.)
