Petrified Forest in October: what the park service says
October at Petrified Forest: the park is open daily, closed only on Thanksgiving and Christmas. Its times are Mountain Standard all year because Arizona does not use Daylight Saving Time; until the clocks change in early November, that leaves the park an hour behind New Mexico and the Navajo Reservation, and on the same time as California. Plan any timed stop with that in mind.
