Description
In Westwater Canyon, Big Hummer Rapids presents a technical Class III challenge with a series of powerful diagonal waves and a tight entry requiring precise boat positioning. Paddlers must navigate a narrow channel between a large mid-river rock and a potentially sticky hydraulic on river right, with the main current pushing toward a challenging recirculating hole that demands careful line selection and strong paddling skills.
