Description

Put In rapid marks the entrance to Keystone Canyon's whitewater section, featuring a narrow constriction that funnels water through tight geological walls. The rapid's initial drop and compressed flow create unpredictable currents and potential hydraulic features, requiring precise boat positioning and careful route selection through the initial rock garden.
