Description
Half and Half Rapid presents a technical Class III challenge with a complex mid-river rock garden that splits the flow into two distinct channels, requiring precise boat positioning and strategic maneuvering. Paddlers should be prepared to navigate a series of powerful diagonal waves and potential hydraulic features on the left side, with the right channel offering a marginally cleaner line but demanding careful route selection to avoid submerged obstacles.
