The Rio de Flag, which has historically been known as the River de Flag and San Francisco River, is a river in Arizona that runs through Flagstaff, originating from the San Francisco Peaks before draining into the Little Colorado River. The river's age is unknown, though its first channels were around over one million years ago.
