Colorful purple, blue, red, and orange crystals in a petrified tree in Petrified Forest National Park, Arizona.
Petrified Forest National Park encompasses part of the Rainbow Forest and the Painted Desert. It consist of several “forests” of petrified wood. Around 200 million years ago, logs washed into a river and were buried quickly and deeply by sediment, which sealed them from oxygen and slowed their decay. Minerals replaced the log’s organic material and crystallized, forming amethyst, citrine, and smoky and clear quartz. The resulting logs are rainbow hues and glitter in the sun. Petrified Forest National Park is also home to many plant and animal fossils and is the site of much ongoing research.
