A neat intermediate run that was closed for many years to the public, but is now open whenever fire danger is low.
The upper parts of the run have some neat class IV bedrock rapids in mini-canyons. The middle part eases off in difficulty with some fun class IIIs here and there. Soggy Sneakers calls it 'intimate', that is a good word for it. Make sure to scout the take out from Mill Creek Park, downstream is a nasty crack drop that does not get run as far as AW is aware of.
Call Weyerhaeuser at this number for a recording letting you know what the current access situation is 888-741-5403
