Weve been running this pretty regularly for the past few years, from neihart down as well. Ran into a nasty strainer last year and had to hike out, not fun. If we were any further downstream we woulda been in trouble as there is vert walls for a good majority of it with very swirly water. Canyon is very dynamic and can be casual class II float at low water i wouldnt hesitate to take a 5 yr down to a very dangerous III+ with IV-V consequence at higher water. This year is the highest snow water equv weve had, so it should be epic and i wouldnt be surprised if the canyon gets choked up again. Im pretty familiar with this stretch and ill say that the canyon can get sketchy, there def has been KIA's. That being said, its the best run close to GF. Neihart stretch is also very fun and fast, but have a good brace.
