Arizona’s petrified wood has its roots in the Late Triassic period, approximately 225 million years ago. During this time, the state was very different from the arid landscape we see today. It was a lush subtropical forest teeming with ancient conifers and other plant life.

As the years passed, the landscape changed dramatically. The forest was gradually inundated by rising waters from the west, creating a sea on Arizona’s western edge. Meanwhile, nearby volcanoes erupted, covering the area in volcanic ash laden with silica.

The process of petrification occurs when wood is submerged in waterlogged soil and remains protected from the typical decay caused by exposure to air and microscopic organisms. Over time, minerals from the groundwater infiltrate the wood through capillary attraction, replacing the plant material with minerals like silica, pyrite, and quartz. The result is a dazzling array of colors that transform the wood’s interior into a rainbow of breathtaking hues.
