The largest natural travertine bridge in the world can be found in a narrow gorge between Payson and Pine, Arizona. Pine Creek flows towards the East Verde River under the 183-foot high span. Formed and shaped by geological processes and carved by this same creek over millions of years, the bridge is truly a natural wonder.
