Description

This is the first tree top horizon line you come to. Scout right side then left if you consider running this. It is normally portaged left. Safety is difficult. The hole at the bottom of the falls can be bad at high flows and the wall on the right below the drop is a magnet for flipped paddlers and makes rolling tough.
