super high alpine, low flow, low quality. one star at best. it will float your boat but considering location and access its laughable. its only on for the sake of completion.
there isnt much class III/IV, a couple miles but again its not really worth it.
rock creek is the west fork of the crystal. that and the east fork join right below schofield pass to form the south fork of the crystal, which runs through the devils punchbowl until it joins with the NF at Crystal City. rock creek has two sections of bedrock on it that can be boated, an ELF upper with some blatant but fun boat abusing drops and a scary lower that holds a 50+ foot falls brent toepper 1st d'd and freddy gnarquist and others have also sent. not really worth making the drive unless youre a V boater or better.
