Although it's hot and dry now, millions of years ago, the land of Petrified Forest National Park was lush and wet, filled with swamps and marshes and trees. The trees died and fell into the marshes where they were quickly covered with sediment and their organics were replaced with mainly quartz and brightly-colored from iron, carbon, and manganese. Look closely at a petrified log and you can still see the tree rings.
