Crossing the Country

Car on Historic Route 66

“Travel is more than the seeing of sights; it is a change that goes on, deep and permanent, in the ideas of living.”
~ Miriam Beard

Saturday:

It is sunny and 71˚ and 8:03 a.m. when I lock the door,
jam my last bag in the car.
No need to memorize the blue of the sky, it is already mine.
A red tail hawk dips into the arroyo,
I catch his wide sweep as I turn north.
Prickly pears and yucca bloom extravagantly,
Spent blossoms of the ocotillo litter the curbside.

In three hours I have detoured twice,
a little lost, I follow Arizona Scenic Highway signs
like dropped bread crumbs in a dark forest,
curve along the edges of copper mines,
open pits of rock, miners in yellow hard hats maneuver
front-loaders along the narrow ledges.

I walk the paths of the arboretum at noon,
detour through Miami’s mission district at three,
at four I descend into the Salt River Canyon.
Hawks soar high above the road, I follow their shadows on the asphalt.
Red Tails are my trip totem,
Road cuts expose the white rock of the White Mountains,
Vines and creeping flowers line the rough rock.

5:02 p.m. and I stop in Show Low,
the motel is on Deuce of Clubs Street, the main drag.
Can’t show lower than the deuce of clubs.

Scattered Petrified Wood

Sunday morning:

Gas at Safeway is 3.42 a gallon,
two fishermen lean against their truck, boat in tow,
and argue about late starts and wasted time.
The older guy draws on his cigarette while pumping gas.

North of Show Low the topography is Illinois flat,
the soil is Utah red.
Dead River.
Querino Wash.
Four Mile Draw, Five Mile Draw, Six Mile Draw.
Godawful flat and dusty,
Telephone poles are distraction.

Past Holbrook, outcroppings jut like layers of floor sheeting.
It’s a land of rock, a many-layered fossil cake in rainbow hues.
Entrance signs greet and command:
“Welcome to Petrified Forest National Park.
Do Not Remove Rocks Under Penalty of Law.”
I take only photographs.

Last Stop in Arizona – Petrified Forest

Petrified Wood

On my second day of travel, I headed north and east so I could visit one of my favorite destinations – Petrified Forest National Park. Not only am I fascinated by the petrified wood – from tree chunks to tiny pebbles – dotting the barren landscape, I also love to wander throughout the rooms of the Painted Desert Inn, a National Historic Landmark, dating from the 1920s. (To be featured in the next post!)

Petrified wood is deep with color, patterns, even textures. No longer wood, these relics are fossils, once ancient wood turned into rock crystals.

The petrified fossils are scattered about the park, but they are protected by federal laws. There are reminders throughout the park, reminding visitors to look, not touch.

Petrified rocks are available for sale in nearby towns, specimens mined from privately owned land. Of course, I had to stop at my favorite petrified rock shop, Jim Gray’s in Holbrook, Arizona.  There is something ancient and sacred about a carrying a small piece of rock in my pocket that is a 100 million years old.

So I added a few last-chance talismans to this year’s Arizona collection of trinkets.

Painted Desert

The Petrified Forest is only a small part of the Painted Desert, an irregularly formed crescent that stretches from western Arizona to central New Mexico.

Pale purple, gray blue and off white striations in the rock at the Petrified Forest add interest to the badlands scenery. These colors came from iron deposits in places with no oxygen, typically submerged in stagnant water in prehistoric marshes. The deep red layers indicate a dry and hot climate in the presence of oxygen. The various layers date from 50 to 200 million years ago, time enough for oceans and swamps to turn to desert a few times over.

I drove through the park, and stopped at every pull-off and a few extra middle-of-the-road photographs. Happily, the park had few visitors on an early morning in late April, and so there were few cars to worry about. And then I drove on the entrance ramp that leads directly from the Visitor Center to I-40 and headed towards New Mexico!

Multi-colored Petrified Wood

“An enchanted spot…to stand on the glass of a gigantic kaleidoscope, over whose sparkling surface the sun breaks in infinite rainbows.” ~~Charles F. Lummis, Some Strange Corners of Our Country – A Forest of Agate, 1891.

Petrified Forest National Park

The Petrified Forest National Park is home to a large region of the Colorado Plateau filled with shards and fallen logs of petrified wood. The fossils have been dated to the Late Triassic period, approximately 225 million years ago.

Annular Petrified Wood

In the National Park, most of the logs in the park have retained their original form as they petrified, but internal structure was worn away by the elements. A few of the logs and some of the collection of petrified animal bones have cells that retained their original organic structure even though the structures were mineralized.

Much of the park’s petrified wood is from Araucarioxylon arizonicum trees, though at least nine species of fossilized trees have been identified in this petrified forest. All of these species are now extinct.

The International School of Gemology presents an informative and in depth explanation of how wood becomes petrified.

Petrified Wood for Sale

My way of thinking, this is a lot of money for an old (thought, granted, very old) piece of tree. Someone must buy the stuff, or they wouldn’t have such big piles of it. The ranger at the entrance to the Petrified Forest National Park did say that the people from Jim Gray’s Petrified Wood Company in Holbrook, Arizona ran a reputable shop–unlike some nearby store keepers who illegally remove the rocks from the park to sell.

So how much would one of these logs cost if they were for sale? Well, we’ll never know, because they aren’t available for purchase. They are located in the National Park.

In response to a Marcie’s question in the comments below, here are some facts about petrified wood that you might not know:

Petrified wood is permineralized wood (as in permanently mineralized) and it is a fossil from a family of trees now extinct in the Northern Hemisphere. The trees are still found in a very few places in the Southern Hemisphere. During the Late Triassic Period – 248 to 206 million years ago – this Arizona desert region was tropical. During seasonal flooding, trees were swept into sandy river channels, and then periodically buried by layers of gravelly sand and volcanic ash.

The ash, which is a source of silica, permineralized the buried wood, replacing the wood with silica. Red iron oxide and pink manganese deposits added coloring in the fossil. Voila!

Petrified wood, of course, didn’t occur overnight. The ocean receded over 60 million years ago, and the wood gradually turned into mineral fossils. Awesome stuff, this geology.
