Visiting Petrified Forest National Park

The Petrified Forest National Park encompasses parts of the Painted Desert and an amazing collection of petrified wood that has been converted to rock, usually some form of quartz.  These shiny fossils of trees (usually portions of tree trunks or branches) come is an amazing variety of colors and are scattered throughout the park.What is now a high, dry tableland on the southern edge of the Colorado Plateau was crossed by numerous mineral laden steams during the Triassic era, about 225 million years ago. The trees that then grew here would eventually die, fall and be covered by silt, mud and volcanic ash carried by the rivers. Over time, the wood tissue in the tree husks were penetrated by silica rich groundwater.  Over time, the silica crystallized into quartz and the logs were preserved as petrified wood.

Eventually this section of the Colorado Plateau sank and was once again covered by sediment from an inland sea.  Tectonic forces once again lifted the area  and from that time to now wind and water have worn away the sedimentary layers and uncovered  fossil bearing material including petrified wood, as well as the skeletons of unique dinosaurs. In addition, the erosion process has also revealed the amazing colors of the sediments in the Painted Desert which have been sculpted into a number of pleasant shapes in a landscape that is typified by colorful, rolling hills.

There are numerous short trails throughout the park that explore the remains of the areas petrified trees. Check the park’s website for more details on things to do while visiting.

The main visitor center (the Painted Desert Visitor Center) is a the north end off of Interstate 40 and is well worth a visit.  Near the entrance, but inside the park is the Painted Desert Inn National Historic Landmark that has been recently reopened. The building functions as a museum and a bookstore (no lodging) and is a wonderful example of traditional southwest architecture.

The Rainbow Forest Museum at the south end of the park has a number of fossil exhibits, offers and orientation movie and is near several interesting trailheads in the park.

One of the main reasons the park was established was to preserve and area of petrified wood for posterity.  Please do not take any of these fossils as a keepsake, as you are denuding this park of one of its greatest treasures.  Of course, substantial fines will be levied if you are caught.  You can buy petrified wood that has been harvested outside of the park at the shops within the park and in nearby towns.
