In this article, we will take a closer look at the history, geology, and attractions of Petrified National Park, and provide you with some useful tips on how to make the most of your visit.


The history of Petrified Forest National Park goes back millions of years, to a time when this area was covered by a vast tropical forest that was home to a diverse range of flora and fauna. Over time, as the climate changed and the forest died, the trees were buried under layers of sediment and volcanic ash, which helped to preserve them for posterity.

It wasn’t until the late 19th century that people began to take notice of the petrified wood in this area, and a number of commercial ventures sprang up to exploit the resource. However, it soon became clear that the petrified wood was too valuable to be destroyed, and in 1906, President Theodore Roosevelt declared the area a national monument.

Over the years, the park has undergone several expansions and upgrades, and in 1962, it was designated as a national park. Today, Petrified Forest National Park covers more than 200 square miles and attracts hundreds of thousands of visitors each year.


One of the most striking features of Petrified Forest National Park is its vast expanse of petrified wood. Petrified wood is formed when trees are buried by sediment and volcanic ash, and over time, the organic material in the wood is replaced by minerals such as silica, calcite, and iron. The result is a piece of wood that looks and feels like stone but still retains the original structure and texture of the tree.

The petrified wood in Petrified Forest National Park is estimated to be between 211 and 218 million years old and comes from a variety of different tree species. The most common type of petrified wood found in the park is from the Araucarioxylon arizonicum, a species of conifer that is now extinct.

In addition to the petrified wood, Petrified Forest National Park is also home to a variety of other geological formations, including colorful badlands, ancient rock formations, and unique landscapes that have been shaped by millions of years of erosion and weathering.
