Description

Surprise: The river splits around a large island. The right channel stays 'high' as it slides past the rock/island, through a couple diagonal waves, then pours over a 3-4' ledge (surprise!). The best line is usually staying left down the 'hallway', then crossing to drop off the final ledge tight to a rock on the right. (Not to be mistaken with going tight right early, ending up right of that rock, in a narrow channel, which is not generally recommended.)

Under-the-Falls: One of the tougher drops to run, to scout, to set safety, or to portage. The right bank is high and well wooded, and rocks at river level are sloped and slippery. A couple ledges form powerful offset holes, leading to odd currents where the flow from the left channel dumps in (see above). Rocks from the left shore (the island) are overhanging (undercut). Caution is urged for those deciding to run this. A common 'bypass' route is to do a 'double portage,' beaching on the island, carrying across, getting in the boat to ferry across the left channel (above it's falls), then beaching again to carry across a hump of rock to a convenient spot to re-enter the river below the drop.
