The Upper Boulder Canyon stretch of Boulder Creek is a fast and manky roadside run. At medium flows this is a pretty stout run. At high flows it is insane, and at low it is much more manageable but bony as hell. The mile above Boulder Falls (Boulder falls is on the North Fork Boulder Creek just above the confluence) is pretty much one giant class V+/VI rapid with just about every hazard you can think of. Below Boulder Falls the creek mellows out a bit to IV+ spiced with the occasional V to V+. Even this lower section is pretty much nuts at high water so usually we end up paddling it at low water when the holes are painless <300 cfs.
