Big Surf is a waterpark located in Tempe, Arizona. Opened in 1969 and financed by the Clairol Company, it boasted the first wave pool in the United States. The wave pool was designed by Phil Dexter. At a ceremony on August 17, 2013 the Waikiki Beach Wave pool was designated as an ASME Historic Mechanical Engineering Landmark. The recognition is for being the "first inland surfing facility in North America".
