Tlargest lizard in the United States is the Chuckwalla, which has a flat body and often reaches a length of about twenty inches. It is native to Arizona and parts of the southwest United States, including eastern California and southern Nevada.
In honor of its prevalence in Arizona, Kingman has a giant chuckwalla statue located along Route 66. It is made out of metal and Italian mosaic glass and has a flatish back meant to allow people to sit upon the large lizard.
