The Petrified Forest National Park is a Scientific Phenomenon

Looking out into the Petrified Forest

Located in northeastern Arizona, the Petrified Forest National Park hosts over 800,000 visitors each year.  Words cannot explain this surreal environment where scattered logs cover 170 square miles. I wasn’t quite sure what to expect on my visit, but what I witnessed was truly an interesting phenomenon.

Throughout the park, fragments of wood seem to have been strewn about for no apparent reason. At first glance, it seems impossible to understand exactly what took place here but scientists seem to have an explanation.  They believe that the area was once abundant with trees which had become fossilized and learned that there were other fossils to be found.  Paleontologists have been studying this area unearthing such fossils as large amphibians, phytosaurs (reptiles), Buettneria (amphibians) and early dinosaurs.

And if the geology of the park is not fascinating enough, there is also evidence of human life with over 600 archaeological sites and petroglyphs.  The petroglyphs are dated between 650 to 2000 years old.

Although seemingly barren, the park is also home to a number of protected mammals which include bobcats, coyotes, black-tailed jackrabbits, prairie dogs, foxes, squirrels, mule deer and pronghorn as well as deer mice.

000 Petrified Forest

I suppose the biggest question is, how did the wood become petrified.  Most of the explanations that I found in my research were way above my head, so I am making an attempt to explain it in laymen’s terms.  Throughout the area there were river channels in the park.  Trees that grew up near the channels, fell down, and ended up in the water.  Over time and on several occasions, residue that contained volcanic ash would bury these trees.  The water would dissolve the silica (silicon dioxide, a chemical) from the ash and would end up inside of the logs.  From here, the silica would form quartz crystals that would replace the living parts of the inside of the tree.  Some of this material would also remain on the outer layer of the tree, giving it its fossilized exterior.  Other substances, such as iron oxide would combine with the silica to create the various colors that appear in the petrified wood.

In addition to learning more about the Petrified Forest, there are many activities available for visitors in the park to include hiking and backpacking,  photography, sightseeing and driving through the park. There are seven hiking trails that range from a half a mile to close to three miles in length.  The trails are named Agate House, Blue Mesa, Crystal Forest, Giant Logs, Long Logs, Painted Desert Rim and Puerco Pueblo.

While humans are the major threat to the park, there are strict rules and warnings for the removal of petrified wood.  It is estimated by the park service that approximately “12 short tons of the fossil wood is stolen from the Petrified Forest each year”.  It would be a shame for future generations to miss out on such an interesting site, but lucky for us, the park was designated a National Park in 1962.
