Signficant waterfall. Located at USGS River Mile 181.
Benham Falls is the most signifigant rapid of this whole section. Typically boaters will acsess Benham Falls from the trailhead on river left. The best put in above the the rapids is a short walk upstream on the trail. After a short class IV warmup section, the river makes an agressive right hand bend into the steepest part of the run. The last short canyon consists of a tight class IV+ rapid with several steep ledges. As the water gets over 1000 cfs, this section becomes class V and is seldom run.
