Description

An espresso hair run usually combined with the middle and lower narrows. The main rapids are Supercollider and Whiteline, both easily scoutable from the road. At truly high flows, only those with the proper combination of expert skills and excessive foolishness should attempt this section.

The most accurate flow information is based on a gauge marked on a boulder at Pine View Falls. There are frequent updates on the Poudre Rock Report website (see External Links) or subscribe to the e-mail list.
