Unkar Rapid

Unkar Rapid at mile 72.6 is the opening rapid of the Upper Granite Gorge whitewater sequence and the entry point into Grand Canyon's big-water character. Built by debris from Unkar Creek on river-left, the rapid features a long, powerful wave train with a significant right-side hole. Unkar is where Grand Canyon trips transition from Marble Canyon's character to the technical Class IV–V challenges of the Upper Granite Gorge.
