After a hundred feet of Class III below the hiker's bridge, grab an eddy on river left and scout this rapid carefully. It begins with a five foot angled ledge right next to a massive logjam. About 25 feet downstream, the river constricts into a 5 foot wide slot backed up by a cave on the left (the hippo's mouth) and a rock on the right, with most of the water recirculating back into a very sticky hole, necessitating a perfectly executed boof. The approach is fast and deceptively tricky, too.The boater in the picture is running the bottom half of Hungry Hungry Hippos. You can see the constriction just upstream.
