This is a narrow, tight stream. There are pinning rocks all over the place. One of the most characteristic rapids is the Cacades, which is a boney slide culminating in a 6-foot ledge. After the Cascades, there's a lot of boulder-bumping. Another good drop is Seven Foot Falls, which requires a committed boof to avoid an undercut wall and hole. The last major rapid is the Slide. This narrow, shallow monster is a portage for many who value their skin and their teeth. _Scout this puppy before running the stream!_ You don't want to miss the last-chance eddy and blunder into it. A small red flag on a river-left tree currently marks the last-chance eddy.
Putin: there are putins downstream of Rte. 381, which eliminate some distance of flatwaterish stuff.
Takeout is the bridge just above the Lower Yough, at Entrance Rapid. Those who wish, can continue on a high-water run of the Lower Yough and take out at the Loop or Bruner Run.
