10th June 2008 - Painted Desert / Petrified Forest AZ Arizona

Heading south from Chinle we were still in the wide open spaces, Mountains are always in the distance. These bluffs are not particularly high because there is no snow on top.
So we came to the Painted Desert National Park. The land is coloured like this as far as the eye can see. Geologically it is the Chinle formation and it extends from here in Arizona about 500 miles to the north west.
Dinosaurs once roamed the earth in this area but today we only have lizards. This collared lizard is the largest reptile in the park. They are very quick.
The body is only about 4 inches long and the tail twice that. To us he seemed a bright green, but the intense sun does tend to wash the colours out.
Just inside the park is the Painted Desert Inn. Now a museum, it was built by Fred Harvey when the Santa Fe railroad passed close by. He gained the concessions for the railroad and a number of the National Parks and so he helped start the tourist industry in the west. His company is now called Xanterra and retains the concessions to this day.
Inside are a number of wall paintings and murals by Fred Kabotie, a Hopi artist of some renown.
This mural is famous and is called the 'Salt Lake Mural'. It tells the story of the Hopi people who travelled up to the Salt Lake in Utah to collect  salt.
In the ceiling are these wonderful glass panels. The inn was extensively rebuilt in the 1930s by the Civilian Conservation Corps to stop the walls collapsing. It was built without foundations and the Chinle formation has a lot of clay. We our familiar with these sorts of problems.
The original building was built of petrified wood, and although the walls are now plastered to give the look of adobe, the door jambs still show the petrified wood collected from just down the road in the days before it was illegal to take it away.
There are the remains of settlements in the area from the period when the Ancestral Puebloans lived on the mesa tops rather than in the cliffs. Some of these communities were quite large. Perhaps the climate wasn't as hot then as it is now. It is thought about 18 families lived here. They left about 1500 AD and are believed to be the ancestors of the modern Hopi.
The scale of this formation is enormous. This type of broken terrain is known as Badlands because it is very difficult to traverse and it has no farming value. There are several examples in the USA such as here and up in South Dakota.
You can understand how people here might have believed the earth was flat, and also why the white man allowed the Indians to live here. Subsistence is barely achievable if at all. But it is beautiful.....
The road through the Painted Desert crosses part of the old Route 66 (Chicago to LA). This ancient rusting auto (though it is not rusting that fast because of the very low rainfall here) and a few other car parts surrounded a sign with information on the route.
Since the area was populated in the past, we were not surprised to find petroglyphs. These are in  an area known as Newspaper Rock.
And the reason becomes obvious when you observe this rock which has hundreds of symbols on it. They can be quite easy to miss until you get used to what you are looking for, then you find them everywhere.
The sandstone clay formations are not always red. Some strata are white or grey, and sometimes quite blue, the result of various minerals being deposited at different times. But there are still those vistas......
Next door to the Painted Desert is the Petrified Forest. Here the wood has been completely replaced by minerals and is now mainly different types of quartz, as hard as stone. This whole trunk across a dry streambed is known as Agate Rock. Pillars and now a concrete beam support it and you are no longer allowed to walk on it. It will eventually crack.
Then it will break into sections as at the Crystal Forest. This used to be covered with petrified wood. But because of its gem like qualities it was hauled off in car loads in the early 1900s to be used for building, furniture and just display. Even today, when it is a federal offense to remove even a tiny part, the rangers reckon they lose a ton a month.
It is very attractive although removing a piece this size might take some doing.
The trees lay where they fell and over the eons fractured into short lengths. There are still examples of large whole trunks, in pieces but still in place.
This is at an area off the main road to one side called Blue Mesa. The red colouration is much less and the blue clays predominate but the same sort of structures are formed.
The area shows a clear example of dendritic drainage - the small washes which drain the water when it does rain look like the roots of a tree. It is constantly changing and reshaping the soils. This is a tiny view of what is a 180 degree panorama stretching out to the horizon.
The alternating layers of sedimentary rocks are shown most clearly here. There were a couple of JCBs in this area but generally there is no evidence of any use being made of this land.
At the southern end of the Petrified Forest is a museum which has some skeletons of dinosaurs which used to live here and fossils which have been found. This is postosuchus kirkpatrickii, a rauisuchian and a leading predator of the late Triassic period
Outside the museum is another area of petrified logs, including some very large examples.
