Petrified Forest in July: what the park service says

A July tip for Petrified Forest: watch the clock. Arizona stays on Mountain Standard Time all year and skips Daylight Saving, so in summer the park runs on the same time as California, while New Mexico and the Navajo Reservation are an hour ahead. Driving in from New Mexico or the Navajo Nation in summer, you gain an hour. The park is open every day except Thanksgiving and Christmas.
