There was once a vast forest here in the Petrified Forest and Painted desert, (a vast expanse of bad land in north eastern AZ).In the desolation and eerie silence petrified wood and dinosaur bones are exposed by wind and rain. At a certain time of year when rare rains fall, the desert is transformed into a painted landscape by flowers, but it's hard for a simple mind to imagine, having not seen.
