Boulder Creek - Starting at the Red Lion Inn, this run is mostly read and run class III. Below the Elephant Butress climbing zone near the mouth of the canyon, there is the crux rapid. Elephant Buttress consists of a ledge hole, a 5 ft slide/ boof, and then a high speed runout. Stay left for the first 2 drops, and then work right to center on the runout. At the end of the run, there is nice surfing at the Boulder Playpark.
