After the previous day at Montezuma Castle, we spent the night in Holbrook, AZ, very near the south entrance of Pefo. So we took the in-park road from south to north, which introduced us to the petrified trees first. The north end of the park is near the Painted Desert.
From the Visitor Center, there is an easy 3/10ths mile loop walk that winds through this petrified forest. So how did these tropical trees end up in a desert? Well, about 200 million years ago, this area of northeastern Arizona was actually near the equator; part of the earth's largest landmass, Pangaea.
Rivers were flowing through the area and these giant trees grew up to 10 feet in diameter. As the super-continent broke up and the trees died or were knocked down (by wind or water), most of them decayed (just like you would expect to see in the forest).
However, some logs were buried by sediment of the river before they could decompose. Meanwhile nearby volcanoes spewed ash into the atmosphere.
Ground water dissolved silica from the volcanic ash and carried the solution through the logs. This solution filled the cells and crystallized into the mineral quartz. Iron and other minerals combined with the quartz during the petrification process, creating the rainbow of colors we see today.
Basically the organic cells in the tree are replaced by the quartz minerals, and other minerals provide the colors we see.
Gives some sense of the size of these tree trunks.
This is one tree trunk; check out the people on the right side of the picture.
Today, this area is very hot and very dry, as witness by this lizard sunning himself on a piece of petrified wood.
Sometimes the earth underneath a tree would erode, creating a bridge. This tree has been "shored up" by a bridge of concrete to support it. The Park Service would not do this today. But I'm glad they did (back in the 30's) so we could see how solid and hard these petrified logs are today.
As we drove north and transitioned from the petrified forest to the painted desert area of Pefo, there was an area called Newspaper Rock. Filled with more petroglyphs (pecked or etched stone), these petroglyphs told about giants (the big figures in the center bottom), dogs, snakes, along with other decorations.
This petroglyph was used to scare children. This bird is carrying off a person (maybe a child?!?!). Must be a very large bird. Check out the person in the upper left corner. Are they trying to startle the bird so it will drop the child?
At the north end of Pefo, we arrived at the Painted Desert Inn. Built in the 1920s and very close to the place where Route 66 cuts across Pefo, it was later run by the Fred Harvey Company (the predecessor to Xanterra, the company Susan and I work for). Perhaps you've heard of the Harvey Girls? It's been said that the Harvey Girls were responsible for the "Taming of the West."
Fred Kabotie, famous Hopi artist who had collaborated with Mary Jane Colter at the Desert View Watchtower in the Grand Canyon, was hired to paint murals at Painted Desert Inn. These are just a few he did.
This is the ceiling of the Painted Desert Inn. WOW! These are glass panels in the ceiling.
Route 66 lives today even though the road itself was decommissioned in 1985. This picture was above our bed in Holbrook. Kinda hard to forget how important Route 66 was during the Dust Bowl, World War II, and then to the early baby boom generation. But the interstate highway system became more popular as the need for speed replaced the time on the road for a family vacation.
This sign describes the place where Route 66 cut across the Pefo main road. The Studebaker jalopy in the background is testament to the millions of people who traversed Route 66 from the midwest to their hoped for dreams of a better life in California.
And of course, no trip to along I-40 and historic Route 66 is complete unless you meet Glenn Fry, standin' on the corner of Winslow, Arizona.
Oh my! It's a girl...my lord...in a flat bed Ford, slowin' down to take a look at me.
Hope you have a great rest of your week.
